Gassy Cream Cake Hydro scrog

Will depend on the source water but if its RO it could be anywhere from about 9-11
You can test this on the bench.

Put some RO/res water in a beaker.

Add agsil. PH will shoot up. From what I have measured in RO it is north of 10.

If you add nutrients to this high PH solution and wait 5 minutes you will see all kinds of nute precipitation at the bottom of the beaker.


The corollary to this is if you add potassium silicate at full strength to a running res, the water will immediately get cloudy where you are pouring it in. This is precipitation forming. So don't do that - any agsil you add to a running system needs to be significantly dilute.
 
There are different settings on the IR gun makes sure its set to surface temp

yes i double checked it's on the correct setting. just checked them again and same reading.. 60-62°

What is the water temp?

70.5, just double checked that as well. same in rez and both plant sites. just to be clear a few days ago when all this was going on i was second guessing all my instruments for accuracy and i had found that my water temp was off, so up until a few days ago my water temp was 74. i posted it a few days ago, i'll go back and look when.. but yeah they entire first three weeks it was 74. it is now 70.

I'm a little confused on the Agsil + KOH. Both will make PH go up. Can you help me with the thinking there?

because you told me to. haha

seriously though you did.. here..

and also along with Aqua helping me in the beginning he taught me that as a buffer any combo of K works better as a team than any one single form of it will.

so i carefully add this to water and use it as a 10% KOH..

On the nutes, I would definitely cut the recommendation in half or more. My personal opinion is lower PPM is better, especially with struggling or smaller plants, as long as you are in balance.

do you think if they get better i should just top off and not even do a change out?

What is the EC trend as it is running now?

very steady Moe, like right at 300ppm the entire time.

I agree new growth looks better.

looks good today too... i'll get some new pics up in a bit..

Oh man... I wonder if calcium was precipitating because of how I was doing this .. and a contributing factor to the cal deficiency...

Always learning, thanks aqua and stoney!

Sorry for hijacking this

no , no worries.. never a hijack hen learning!!!

i've done it this way because i had no bad habits when i started so i was taught the textbook way and just continue that way.

plus at the time Aqua was helping get my solution figured out and was making test batches that were sitting overnight so it was all taught i good practice.

You can test this on the bench.

Put some RO/res water in a beaker.

Add agsil. PH will shoot up. From what I have measured in RO it is north of 10.

The corollary to this is if you add potassium silicate at full strength to a running res, the water will immediately get cloudy where you are pouring it in. This is precipitation forming. So don't do that - any agsil you add to a running system needs to be significantly dilute.

i mix mine up in a 7.8% liquid solution as per mfg and then add this liquid to my water barrel. first i add half the water then the agsil liquid then the second half of the water. then ph down then i let it sit for 30 minutes before adding the cal mag.

Recipe for 7.8% Solution:

780: 1
148g : 1 L
560g : 1 gal

Mix 148 grams AgSil 16H into 1 liter water or 560 grams per gallon. Store in bottle or jar and shake well before use. (1 lb = 454 g). Use this 7.8% solution at 1/4 - 1/2 teaspoon per gallon water.

WARNING: Causes eye and skin irritation. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling.

Never mix concentrated silica solutions with other concentrated fertilizers. It is best practice to make up the liquid solution first or add water prior to mixing the powder with other ingredients or nutrients.

When mixing, be sure to add water to the container first. Fill the container halfway with water and then add the Agsil before filling the rest of the way and then mixing thoroughly.

.

so far this has worked well for me at 2ml of 7.8% per gallon of water. then another ml per gallon of the KOH. this brings my water up to about 60-70 ppm

100% this. at least diluted 10:1

I remember this. Its because the agsil wasn’t buffering well enough.

Yeah of you can get your res temps 70-74. Reduce the wind to 0 to prevent evaporative cooling and raise air temps to around 80f then i really think your problems will end and they may well do fine with that amount of light

I really think the wind and cool plants temps are the root causes
 
I remember this. Its because the agsil wasn’t buffering well enough.

it was that armor si that wasn't working well. once you had me get away from that it's been much better. ph is about the only thing i don't have an issue with anymore.

after i got more comfortable with it i made another test batch with that armor si and it was a total failure yet again.

Yeah of you can get your res temps 70-74. Reduce the wind to 0 to prevent evaporative cooling and raise air temps to around 80f then i really think your problems will end and they may well do fine with that amount of light

the fan has been off, well last night i put it back on setting 1 and pointed it up at the ceiling to move the humidity and heat around. no wind on the plants at all.

i just turned up the heat to 79 this should keep it right at 80.

and once they recover do you think i can start to add more light? just a little?
i mean man i just got another light to put in there!!!!! there's gonna be two of those 550's in there just like in my other cabinet!! not maybe, it's gonna happen. i already have the light...

i'm gonna need it for flowering, one is not gonna be enough.

i won't overdo it.. i understand. but there is a clear reason on why one plant is smaller than the other and thats the light placement. it's not centered correctly over the buckets and the left plant gets the sweet spot. soon they will both have a sweet spot!!!

i know you're shaking your head at me right now... hahaha

thanks, good to know it's things i have on hand if needed and nothing special.



i'm sorry guys it was just some coco..




i'd like to go over that with you guys.. so if i do a full change out my plan was:

25 gallons rain water 9ppm

agsil 16 mixed per mfg @ 2ml per gal added
also 10% KOH @ 1ml per gallon
the total buffer normally gets me to 60ppm
then immediately add enough ph down to get me just under 7.0

then after 15-30 minutes of mixing i add 25ml of calimagic

then i add nova grow, i haven't determined the amount yet. Gh chart suggests 4ml/gal for 800 ppm, i was thinking of going half that at just under 2ml/gal and aim for my entire solution to be 400ppm. i'm at 300ppm right now.

then the mr humic (whatever the recommended dose is, i don't remember off the top of my head)

and lastly 12ml of each orca and king crab

once all mixed i check the ph and adjust. most times it's real close or right at 5.8 once there i pump into the rez.



there is no foul smell whatsoever. i have some of this on hand > https://www.kelp4less.com/shop/enzyme-powder/ could i use that?

whether i do a change out or not my rez is about ready for a top off. so if this problem is environment then i need to at least start the top off measurements in a couple days.

.

so is it just me or do they look better today? seems to have more vigor?

Thanks everybody!
was that spectral ratio cooking them with combined environment of not being able to handle the light?

Nah your all good bro. As for the light just play by ear. See how they look after 5 days then if you post a pic i can look at leaf orientation.

Your ideal leaf temps are around 75f so see where this takes you and go from there

possibly but more so a concern for the low leaf temps causing slow viscosity within the cells.

lowered the light intensity and raised the temps. in holding pattern to see if it goes away..

i didn;t measure the temps on the soil plants yet.. i bet they're much warmer. once the lights hit 50% power the heater doesn't need to run. for some reason i don't mind paying for light power, heater power feels like a rip off!! haha

i'll get some close up later tonight and see how they look. right now i don't see any curling.

so what do you think caused the burning? was this just slow metabolism and thick fluids that the leaf just couldn't provide for itself?

well....you could bring the light closer to plant to keep the leaf temps up higher, and just turn the PPFD down slightly to match the difference...but more adjusting and balancing...

one way i see it, higher ppfd is more energy to the plants, therefore they may need to pull more nutrients, might not be able to if the variables that dictate nutrient uptake are hampered.

Some of my best grows had the leaves praying.

I like to push things. But results like Stoney is getting are common if I go too far in one way or another.

@Stoneyluv I promise you can use that light to its full potential if we get this dialed back in.

Tell me about the genetics. Have you grown this before?

Your roots are too small to get the full hydro advantage. If this were my grow I’d be focused on root growth once you are happy you are back on the fairway. If everything is back on point the root growth should outpace the green growth at this stage. If it does not something needs tweaking. Daily pics of roots would be helpful.

Since your ph has been so stable additional bubbling could not hurt. I’ll also pack up and send you that do probe tomorrow. You will need do calibration solution I’ll send you an Amazon link when I get to pc.

Res temp of 72* and max do for your altitude is the goal. If your Bennie’s load contains fungi too that’s preferred. Pretty amazing the symbiosis if you never looked up what that does. What is your elevation?

I know paying for heat sux but I’d push the tent up to 80. That will make them drink ;bbuild;mred

How is your co2 level? I’m assuming lung room around 400?

At this point in veg I would set to 800 and head up to 1200 in flower. Not sure if you have co2 but if so on healthy plants in flower you can use every bit of that light you have there. I run maxed out most of the time in flower. Then you won’t need any heat your problem will be humidity and cooling it down lol.

I’m thinking it’s time to cull those questionable leaves at the bottom.

I’m a little concerned you have too much k. koh and pot sil and

It's funny when knowledge explains reality..

This cloudiness just happened to me for the first time last rez change... Saw it when adding nutes to the mix... And probably because I had a lot of silica in there following the ppm chart aqua shared with me.

I'll be changing the res this weekend and following this new step. It's my fault for not asking what that was last weekend..

@moe.red do all nutes precipitate at the same rate in this scenario?

@Stoneyluv thanks man for letting me get that knowledge here in your thread lol

Nute ratios look good to me… i agree praying is good to a point. Ideally i look for the top 3 node to have leaves slightly V shaped and the lower flat. This seems to be about my limits before light stress. With co2

i'm confident, i let horsepower fly on the first grow when they were in flower, i just gotta have patience.

no, but a few peeps here have, G$ has.

i was hoping for better roots Moe, it was the #1 goal this grow and it's better than last time with the hydroten but this isn't good enough. i have this coming tomorrow...

ince your ph has been so stable additional bubbling could not hurt. I’ll also pack up and send you that do probe tomorrow. You will need do calibration solution I’ll send you an Amazon link when I get to pc.

yeah i opened up all the valves a couple days ago.. it's running four stones so it's not over agitative at all.

es temp of 72* and max do for your altitude is the goal. If your Bennie’s load contains fungi too that’s preferred. Pretty amazing the symbiosis if you never looked up what that does. What is your elevation?

i'm just under 1k feet, like 960 or something like that.

know paying for heat sux but I’d push the tent up to 80. That will make them drink ;bbuild;mred

i understand, already accepted it! turned it up earlier and running right at 80 now. giving it a few hours to stabilize and check the rest and get some pics too.

How is your co2 level? I’m assuming lung room around 400?

yeah it's low, maybe better than 400.. i don't remember. i go put my meter in there now..

At this point in veg I would set to 800 and head up to 1200 in flower. Not sure if you have co2 but if so on healthy plants in flower you can use every bit of that light you have there.

i don't have any source of co2, what i got is what i got for now..

i wanted to ask if it's okay to do that.. i'll trim em up now!!

we're all learning man.. your plants obviously look better than mine so i'll suck up any knowledge i can!!

Starting to think k overdose.

View attachment 91322


K fights with everything

do you think i'm adding to much potassium from the start?

do you know what a good starting ppm of K would be? (considering i'm adding about 200 ppm of nova grow)
 
View attachment 91325

Interesting on the cold tolerance.

K has a direct connection to stomata. Wind, low temp and loss of control of your ability to move water thru the plant sounds like a bad combo.

wow it looks to have a direct connection with everything i'm experiencing.

i had small brown spots and yellowing too.. you add up the high K, bright light, fan wind, and cold and all together it could be the disaster.

i'm gonna go tak pics now and put my co2 monitor in there..

all sounds good man.

Healthy growing plants like high k. On a target mix of 300 ppm about a third could be k. I like it closer to 60 k and 250 ppm total when they are young tho. But it’s harder to overfeed than underfeed k.

If you get them really drinking lower ppm is better. Think of the way smoke does it.

I use gh flora so I have 3 bottles to your 2 or 1 really at this stage. I sure hope that mix is right because I don’t see an easy way to change your ratios other than dropping the potassium silicate and koh.
