Make sure the soil dries before watering again (for my 5gal pots that's every 4 days @ 42% humidity). Make sure the temps aren't too high, don't let the canopy go over 84f. Also make sure you have a slight breeze from a oscillating fan, they need to just jiggle ever so slightly every 15 seconds. Too much constant breeze will give your plants wind burn and you don't want that.
And lastly light make sure to follow this below. If you don't have a LUX meter you need to get one.
Seedlings, 10-15k LUX
Veg, 20-30k LUX
Flower, 35-45k LUX
Do NOT go over 50k LUX you will bleach your flowers.

Heat stress. And you need an injection of calmag.
If u don't have any calmag hand, u might have Epsom salt make sure there's no menthol r anything like tat in it.
A 150-200ppm of ES added 2 ur water will help..

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance.
Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

Stickstoffüberschuss?Habe bei meiner Auto das Problem das sie kaum in die Höhe wächst, dazu die Flecken auf einem Blatt. Ich habe aber das Gefühl das die anderen Blätter auch zu dunkel sind? Vielleicht wächst sie wegen einem Stickstoffüberschuss nicht mehr?Sollte ich erstmal ohne Dünger gießen?

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.
