Day 147- Flowering day 47- Wooooo this girl is lookin rough lol I have a theory though. I may be over feeding which can cause a K deficiency. I’m not sure though because the last plant did the same thing and I only gave it water for a week which didn’t help it get any better. I’ll try actually flushing it to see if that helps.
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.
