That’s from over watering man. Your soil isn’t draining fast enough or your over spraying them.
Keep them dry and add a nice fan to help with air flow

I'm not sure what's going on, but the tips of several leaves are twisting over and/or turning white. I don't know if it's a nutrient deficiency, nutrient burn, I don't think it's too much heat, but maybe due to sun burn? I'm not finding much luck about white leave tips online.Week 7

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

Cal Mag from LED too close?Brown spots on upper leaves mostly. Light was at 14" from tops, Mars says 18"-24". Top leaves got light bleached too. Moved light to 22", recalibrated ph pen assuming it's cal mag, given 2 feedings @ 1tbsp cal mag/gallon. Any other possibilities? Not bugs, I scoped it.

Spraying the leavesWhile I was checking my plant I saw these “black stains” like the plant is “half-bitten/scorched”.Is it possible to burn my leaves and create this effect after spraying them with nutes. Blacks spots were created today after I sprayed them and there were drops on leaves for hours

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

Weird looking seedlings? (uploaded vid)My seedlings, especially Seedling 1, look kinda weird to me. Seedling 1 appears to have some weird yellow spots here and there and the leaves look cut? They just look really weird and not like normal cannabis leaves, both seedlings have their leaves going up at the corners.6y ago
