I've read that it's a boron deficiency, but I'd rather be sure.

First photo mechanical damage to stick from wind and brushing. Second - clawing leaves, nitrogen toxicity. Slow down with food ! Less is more in weed growing. Golden rule !

Brownish Spots on 2 Older Leafs. Young plant.
I searched it up before posting this and what I found is: Leaf spot, canker, and fungus: Brown leaf spot, Yellow leaf spot, Cladosporium stem canker and Chaetomium fungus. Solutions I found in the comments below. What do you guys think? Can it be heat (a lot of hot days here)?

Yellow/Brown/Spotted/Crispy Lower Leaves
What is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

Been discovering these little burns and holes on all the plants, Pic 2, 3 and 4. I'm assuming the burns are the precursor to the holes but I'm unsure, maybe they're not related. Any clues as to what this is. I want to stop it ASAP Rocky

What kind of deficiency? What should I do? By the way, they're autos.
What kind of deficiency do I have going on here? I gave a good dose of calmag last night. The first signs were the dark spots on the leaves. Been feeding ff bloom nutes every other day, 1/4 to 1/2 strength. started from the bottom. Leaves turn yellow and then dry up.

Did I over-egg the nutes?
The leaves turned like this after a feed and a Mosquito Bits treatment, guessing I over-egged it with the nutes? Plants getting close to me cropping them, might leave them to dry out from their last water then chop.

Spots on leaves, because of transplant, new light or overwatering in week 4?
The leaves have some brown spots on it, is it because the overwatering last time (like I think) or do you guys suspect something else..?
