Advanced Nutrients in promix

[Speedypete]

Hey Im new and have a question about salt buildup in promix looking for some advice. I just flipped to flower after a 4 week veg. If it looks like my plants are a bit on the lighter side of green doesnt that mean that there isnt a risk of buildup so far? After reading post after post on other sites i dont know what to think. Some say water/feed to runoff… some say not to water/feed to runoff as it washes the buffer out of the medium, some say feed/feed/water will help the plants use up unused nutes in the medium that causes buildup is sufficient. Some say theres no need to flush or water through unless they have been over fed. Im thinking if they look slightly underfed there shouldn’t be any need for runoff. Any input would be appreciated on how people here make salt based nutes work in promix Thanks

Thanks man. I saw issues at 82 but i think it was my own fault with ppm too high. Lots of great advice here. This is my second grow. I tried rdwc first with not much success. I figured i should start with something simpler so here i am in promix. Learning alot.

Promix is a very very forgiving soil, ive been happier than a pig in shit since i switched to promix. Makes things so much easier when you start at 0

We got great hydro guys here.
More of them and cocoa than dirt.
I love dirt and mixing different brands~!
You're doing great~!

Runty at 65 days There was a time i didnt think she would make it

I am turning down my light intensity and running cooler temps in the last couple weeks to mimic fall. Does this increase trichome production

Going to start this with NO PRO here and this is just my understanding. I have been wrong before.
My understanding is photosynthesis and heat create trichomes. I would think the lighting duration would be the signal the plant receives to crank up trichome production. Many believe that trichomes are a kind of heat protection and therefore created by heat.
That being said reduced light strength and temp help keep terps and trichomes from evaporating or drying out too quickly or in excess.
If you smell it they are evaporating or deteriorating.

Thank you

Soo, what you got cooking now?
Your past grow looked great.

I did the same strain again fruity pebbles from quebec. Had some problems at the start. They are 8 wks in now I will probly go 9 1/2 or so with them. Am trying running lower temps to ripen Currently 77 and dropping day 62 night rh 45%

Looks great man~!
Many reduce light strength to help the plant finish up also along with lowering temps to get more color if possible.

Thanks I am down to 75% intensity and cut lighting to 11/13

 

[steamroller]

I have a finisher at 50% now.
It is just one light over the one plant in the room that is 100%.
Generally I drop down under 75% before chop.
I try to get night temps in the mid low 60s if I can.
Day time 77fis as high as like last 3-4 weeks.

I was wondering about how low to take intensity. Thanks mang Will try lowering more yet

The effect of cold on cannabis plants

In this post we show you which methods you can use to avoid the cold in an indoor cannabis crop. There are various modes to keep a stable temperature during the winter so you can choose the resolution that best suits to your indoor or greenhouse crop for personal use.

other way around would work better, turn your light down to about 65% and increase your hours on to 13/11- 14/10 or 18/6 for the last week, its too short a time to reveg and they get a boost from extra hours of light at low intensity. 7-10 days closer to 7 than 10

The key is to get the humidity way down the last 2 weeks. Lower humidity increases resin production as a form of plant defense to help it from drying out and deflecting the sun or led's rays. Or at least that's what "they" say, who ever they may be.

100% agree with Pipecarver!!!!

Anecdotal/Broscience alert!!!!

When I flipped the last crop, I set the DLI to CO² level at the first sign of flower without using CO². I left it at that level for the first 5 weeks then dropped it incrementally until I got to the suggested DLI in week 9 and kept it there to harvest. When I did a closeup photo of one of the flowers there was an abundance of trichomes all over the flower at a pretty early stage in contrast to the first time I grew it. I'm attibuting that to the plants defensive mechanisms and my manipulating that by exposing it to higher than normal levels inducing the plant to put up more trichomes in defense.

It could be that I've figured out a way to increase trichome production or it was just the genetics but it seems to have worked well. I'll continue to try this out on different cultivars to see if this technique can be consistently achieved.

Dropped my light intensity to 79%, temp 75 on, 66 off and humidity 45%
