Day 43- So I’ve learned that these Blue Dream seeds are regular seeds and not feminized. Idk if this plant is a male or female, just gotta wait for it to show me its preflowers. Gave it 1L of nutrient solution this morning. I might top this thing one more time in a few spots to get the lower outside branches to catch up.
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.
