It seems like they darken like that with time. The stems on the older fans are darker than on any of the newer growth. It's lights off right now but I'm almost positive that's how she's been growing so far.

Is there something to look out for with the pinker stems? Her main stems have a really dark purple pinstriping.

Not sure if this was covered but without avg leaf temp differential entered in the controller 69 settings, the displayed vfd has not been accurate in my experience. I only use vfd for quick reference but C69 can also automate around it so ymmv.

I tend to agree if you want to get serious about this.

You can also make due with what you have if you are just dabbling. It would not kill you to wait a grow and see. And then on grow 2 you will be flowering in the winter, so not as necessary then.

If you grow big plants in my area in the summer, a dehuey is only optional if I am prepared to deal with bud rot.

So I kicked the fan's minimum up to 2 and it's forced the heater and humidifier to run almost twice as often as through the night required. I think I'll start shopping around for a dehumidifier, but the fan seems to be bringing in enough dry air for the humidifier to be needed. That just means I have a little time to get it figured out, not that I won't buy one. It's not worth the risk, as this may be my only harvest for a while. No way I want to hit the road without a harvests worth to get me by.

Yeah I've checked the leaf temp and it's pretty consistent at 2-3 degrees below tent temps. That's where I set the 69's leaf offset.

@Aqua Man - Is there a degree to this effect in hydro vs soil? I've run high humidity through veg and not run into this problem. Is there a slower uptake in soil due to cationic effect so environment doesn't affect it as much?

Ill get back at this after work because i think the convo will get deeper and want to give it a good deep answer and follow up.

So last night we determined that my VPD needed adjusted. We're now running seperate day and night settings at 79/72 degrees and 55/51% rh. I've already noticed a big change in the humidifiers runtime. This leads me to believe, as the plant grows and progresses into flower, I'm going to need a dehumidifier. Last night, the humidifier only kicked on once, for a minute, when the rh hit the low limit.

Does anyone have a brand of dehumidifier they'd recommend? I'd like one with a manual switch so it can be ran with my 69 pro.

Toshiba i really like. Been beating on it for years now. 50 pint will do for a 4x4 but the 70pint with auto restart function (super important) and a drain hose attachment would be ideal
 
It's hard to see any improvement on the leaves in question, but overall I'd say she has responded well to the new environmental conditions. Half inch of vertical growth and she's nearly covered the tote completely.

She's nearly 10 inches tall and the tote is 16x21. Pretty squatted but she's really bushing out. I think she'll fill a 3x3 no problem.

You wont see any improvement really on the existing growth but newer leaves should not be swollen and the issue should not progress to nee leaves. The old leaves will get worse and be aborted by the plant.

They dont waste energy repairing leaves but instead just grow new ones.

Ok. So don't be alarmed if I see the fading on some of the fans get worse? Makes sense.

Its more to deal with the osmotic pressure and to an extent o2 as its a requirement for plants up take nutrients. This is why its best to water around lights on. Light drives photosynthesis and transpiration.

There are many factors that all contribute to this but cooler temps and higher humidity will slow transpiration. Its a combination of several things in his case.

You can look up guttation to get a better idea how this happens as part of the equation. Its not so much the guttation thats the issue but the constant high humidity restricting the uptake

Yeah thats a better term i guess. It’s basically root pressure and humidity.

You see how many say oh my leaves are praying to the light thats good.

See it is and it isn’t the extent of that is turgor pressure. The more light the more pronounced this is in a sense… its an indicator of light, transpiration and pressure in the plant. Not always good or bad and is a great visual queue to diagnosing problems.
 
I'm thinking she's gonna pop this week @Aqua Man. She's loving it in there. Thanks for quick assist with my VPD issue.20230628_182823.jpg
You can see some of what I was calling Mag deficiency on the fan that's leaving the picture on the right side. I'm gonna try my first attempt at a foliar spray tonight, if I can stay up passed lights out. Will 30 minutes to an hour of early darkness hurt anything?

A sour smell appeared today. Nice and dank.

Can do it about an hour before lights out out at the beginning or hour before lights on is probably better

That's an hour before I get up so that would be pretty doable. Anything in particular I need to keep in mind?

I predict you will get some bud off that plant. I'm like at least 70% sure ;)

Appreciate you jumping in @Aqua Man sometimes I get a little too busy for my own good and leave people hanging.

Man I hope at least a fat nug or two 🤣

You're good man. I know you've got a lot going on and Aqua seems to be like the all seeing eye around here. Like he's always watching knows when we've been bad or good.

Overslept and missed it this morning but good thing. I wasn't even considering top or bittom side of the leaves. Bang on Aqua!

The theory is you don't want drops on leaves to act like small magnify glass and burn the leaves when the sun comes out.

Noobass tip not sure where you have it but dont forget to move your controller probe out the way before you start misting like I do almost every damn time lol.
Click to expand...
I've done that before!!! 😄

I freaked out for a second seeing my humidity hit 87% until I remembered I had just moved my humidifier to a new location so I opened the tent again and, sure enough, the vapor stream was pulling across the probe.

I spent an awful lot of time watching the vapor trail in the tent. Ended up in the tent in just watching from all corners 🤣
 
Opened her up a little last night with a trim. Took off a couple fans and some stuff on the lowest stems. She grew another half inch overnight. That's an inch total yesterday.

I avoided the epsom foliar treatment this morning considering I gave her a trim last night. Wasn't sure if that would be detrimental to the healing process or not. She'll either get sprayed tonight or tomorrow morning.
 
What EC are you at now? Growth rates look good but thinking you may need to up the EC a touch more

I'm at 510 on the 500 scale.
Aqua Man said:
You can add 1 gram per gal to the water the plants take it up pretty easy. Much easier than foliar spraying imo.

I added 3g to the resevoirs the other night when we first talked about it. The affected leaves don't seem to have gotten worse since. That's 1g/5gal. Maybe I'll add a bit more tonight.

If its fixed more wont help but at 1 gram oer you are not at risk if any issues from it either bro
 
We were at 470 until I added the epsom. That brought it up to 520. Couple days ago.

Are you suggesting adding more epsom to bring it up or another dose of base nutes including some calmag?

Nothing at this point… you can add a bit more epsom but with RO id wait another week to see the full response
