Brown and straight with spots is potassium deficiency signs. Also check pH in substrate to ensure it is not a lock out front that. If that is is range then I would increase potassium level.

Damaged leaves
I have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not corrected

Brown spots, serrated edges curling up - calcium deficiency?
This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up. Is this just a straight calcium deficiency?

How's the quality?
How would you rate the quality of these plants? The dark brown leaves have me self conscious of the roots situation. DIY supersoil mix recipe here: https://pastebin.com/pbxMZysq I've added more dolomite & guano as topdressing and fed liquid calmag and potassium during flowering.

Why did my pistols turn red so quickly? I did add some neem oil and recently began running CalMag but immediately stopped... Finally got ph tester and realized I’m running way to high. Got up/down coming. Any ideas??? Should I worry or do anything? Also, no males in there

Ph issues part 2
Hi guys! It has been a while after flushing, repotting into bigger pot with fresh medium and feeding her only with water. I bought Sensi cal mag extra and I need your advise if it can be used together with BioBizz nutrients, I could get only this brand in my local store

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

Brown stains on leaves edges
The top leaves on my GG#4 started to get brown on the edges. Initially I thought it was light burn, but the stains kept progressing after I readjusted the light distance. Is it a nut burn?

Curled leaves and brown spots
Please help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?

brown spots began to appear, could this be due to watering with PH 6.0, maybe too little and calcium is not absorbed? PH of water with each watering 6.0
