What kind of deficiency is this?
Ezzjaybruhanswered grow question 5y ago
I believe this is potassium deficiency.
K deficiency causes internal temps of foliage to rise and it causes the protein in the cells to burn and degrade. Usually happens on the edges of the leaves.

Dried Leaves, Lockout or Stress. Week 5 of FlowerPlants suddenly wilting & looking crispy like they're dry, but pots are HEAVY! Suspecting root suffocation/rot ("wet feet"). Hard soil crust might be blocking oxygen. Roots are drowning & can't drink. It just happened yesterday since they look dried. Temp is 25C and Air 50%

Plant seems to be dying, should I flush? And if so, any tips?Yellowing & wilting, I suspect the problem is too much silica boost .5ml every other water, combined w/ hot soil (FFOC) & a few feedings, & maybe underwatering(?) as I never have runoff, watered a cup or so every ~48hrs, when soil had dried. LST, no wild temps/hum, great airflow.

Yellowing on GT and clawing on CBI'm seeing an issue with Ghost Toof. The lower leaves are burning it seems. It looks like it could be a K(Potassium) issue, or possibly nutrient burn.
Also, Chem Bear seems to claw quite a bit. I don't think I'm overwatering... so maybe a Nitrogen issue?6y ago

Dry or Feed?What should I do to fix my plant? She has hanging leaves and yellowing for weeks. The summer has been pretty wet here, and the soil has been satiated a couple of times. It's getting dry now. Should I wait for the soil to completely dry or try feeding nutrients?5y ago
