First try to LST a plant. Not sure why the fan leaves curl up, noticed the water was basic and got it normal. Raised the hps up a couple more cm, I have a fan moving air in the bud site. One branch shows signs of yellowing.
I found that my tap water which I’ve been feeding my plant has a pH of 7.4-7.3 which must have been too high, especially after one generous watering I made. Prepared water with pH of 6 and a humble half scoop of generic blooming plant food nutes to even things out, will see if that changes anything.
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.
