I've had this before, mine was due to calcium/magnesium deficiency, are you using calmag as part of your feed?

Brown spots on top leaves - nutrients, light or something else?
She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help

Possible calcium def. or other issue affecting leaves and buds
Is this a calcium issue, and if so why is it spreading to this one bud in particular? There are four photos of the effected bud, as well as a few shots of unaffected buds to compare. Also have spotted leaves that look like ca issue but not sure why its spread to the one bud.

Is this pH related?
Hello, mates! Anyone knows what this could be? Searching I found that it could be pH related. I use pH controller from ferts (pH perfect from advanced nutrients) since the beginning, so I think it's odd that it could be a pH issue. p.s. 3.5 weeks of flowering Thanks 🙏 🙏

On my OG Kush plant my leafs are starting to look “Plasticity” just not the same as it use to. Also the OG seemed to stop growing, no change in height or bud sizes for the last week or so. Watering/feeding along side with my white widow every few days.

I came back to my plant today and noticed issues with a bunch of the older leaves. Is this calcium excess?

Bugs creating holes in leafs?
Does anyone know what this could be from and the best course of action? I can't find any visible bugs on topside or underside of the leafs. Have been putting her outside for a few hours each day for the last week. Nute burn is from hot soil from bottom of the pot she grew into..
