I think you know the answer to this question already........... Good that you are experimenting, but cannabis plants really do need "sleep".

What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Getting out of the ideas - VPD, nutrients or deficiency?
I'm getting out of the ideas as the foliar symptoms proceed. Lowered EC down to 1.8 from 2.2, pH in range. VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C

Unhappy leaves
A few leaves aren’t looking too happy. What’s that? Deficiency’s, too much light, too many nutrients? It’s only a few leaves with that problems. What should I do, what would you do? Thank you!

Guess on what this is?
Unsure what this issue might be. PH seems in check going in and out. Getting mainly Fox Farms nutrients - got very weak doses of B-52 and CalMag a week or two ago. The other two plants are fine.

LEAVES AFTER FLUSH
When I flushed my plants all leaves went looking down as normal, but now that they dried they kept that shape and the tips that are really dry (due to previous overfert) are curling all weird...is it ever gonna go back to normal? Is it still good anyways?

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Yellow and fragile leaves 2 week
Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

Strange leaf deformation
Have these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though Cheers

Deficiency?
Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else. I'm using the BioBizz outdoor trypack (BioBloom+FishMix+TopMax) Currently 2ml/L each. Symptoms are shown in the lower leaves. Maybe CalMag? or Pk 13-14? pls lmk
