Help me ID my leaves diseases

Ok I have two plants with two different diseases. At least I think so.

I am growing in small pots using organic potting soil and GH (Non organic) ferts.

Any ideas?

Oh and no the second one isn't from mites

well it could be two things to much heat or nutrient burn

and bigger pots might help

how big of pots are you using? They may be rootbound, but it is hard to say without pics of the whole plant. It could be rootbound in combination with over fertalization.. what lights are you using or is it outdoors? etc...

My setup

1 Gal pots
600 HPS on a track(short track but it helps prevent burning)
4'wide x 5' long x 4â??H (32â?� to the hood of the light)
85F ambient temp
35-45 humidity
Constant low lvl CO2 bleed with steady venting (Not a fill and purge cycle)

Likely root bound yes, but I am trying to stunt them slightly because my space is limited. I use a light hydroponics solution because I figure they ARE root bound and need the complete span of nutrients.

With all that power in such a small space am I just going to have to concede that this will happen from time to time?

Hey buddy I have some leaves that look VERY similar to the center and right pictures and I've got tiny black spots under the leaves. However, the affected leaves are not brown speckled, but pale speckled. I just found it out a few minutes ago, I thought it was a nute problem but its not.

if it isn't a nute burn it could be a deficiency of some sort... did you add dolomite lime in with your soil and what is your soil ph?

I am adding a bunch of micro to see if it is a deficiency. I also picked up some foxfarm ferts for soil. I think I can lightly fertilize my way out of this one.

I will keep ya’ll posted

Thanks for the input

BTW paulinator make sure the black dots aren’t mites.

Hi my fellow grower.

It is my humble opinion that the first pic could poss b nut burn,

But i feel more strongly that the third pic could very well b a Mag def either through nut lock up or too much hard water.

Where does ur water source come from, Awell or town water?

I suggest mixing 1 tablespoon of epsom salts with 1 gallon of water and water with that sol for a few days and see what happens.
U can also mix 1 tea spoon of e salt with 1 litre of water and use as a foliar spray for a week
doing both would b fine.

R they drying up and crumbly from the tips in?
