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%

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Wilting and turning yellow. Let them dry and flushed with PH water but no changeHey Guys
A few days ago, 3 of my girls started wilting and turning yellow from the top down. Figured I must be over watering them so let them dry out (checked with soil tester) then flushed with PH water but no change
They're in 4th week of 60/40 batmix so not fed them yet
