Wen a lil over the top this week as there are signs of nute burn. I have to move the pot when watering and a second branch snapped while moving because it was so heavy. Feeding only pHed water will see what that gives
I would like some comments about these yellowing leaves on one cola and also the upward curled leave edges. I am not sure of the cause and relation of these signs
The leaves that appear to be pointing up are fine, but the leaves with discolored edges are a classic sign of potassium deficiency. The slight canoeing is probably just from a really warm day in the past few days, I wouldn't worry about that.
