Drooping leavesI have a 2 week old plant that have drooping leaves, so i researched a lot and the most probable cause was over watering, so I spaced out waterings and let it dry up almost completely but to no avail. Could it be its current pot is too small?

Check plant n4 on my diary. Can you notice what's wrong?My N4 on the Underground Pleasures diary is a bit strange. Can you notice from the pics?
It is a bit droopy because it's night time for them but the problem is the clawing and has a paler green than the others.
I flushed it with PHd water and keeping nutes by half the strength.4y ago

Leaves are a little droopy ?Transplanted her into a 5 gallon and added 2 tbs per gallon of 444 and then I topped her last week and been watering from a ph of 6.3 -6.6 could it be over watering ? Or nutrition burn ? I water when the soil gets dry with a sprayer and I dries out within usually a day or so

THIS IS NORMAL?It's been 1 or 2 days since some leaves started looking like this. It seems to me that they're curling down or a bit sad, even though they're still growing. I would like to start feeding them today, but the pH and TDS/EC meters won't arrive for another 3 days. Should I be worried??

Cal mag or nutrient BurnI have 3 Automatics.
I made the mistake of planting the into BioBizz Allmix, which is pretty strong for Autos.
Strawberry Gorilla and Aplle Strudel seem to be fine.
My Orange sherbet not so much.
Is this Cal/ Mag defficiency or nutrient burn?

Fertilizer burn or something else?Hey fam. Plant seemed fine a few days ago besides a mag deficiency.
Decided to foliar spray cal mag at half strength a few times.
Now there are brown patches and leaves/stems are curling down like they’ve been overwatered.
