sir_isOanswered grow question 3 years ago You're using peat and coco and you added lemon juice to rainwater? That to me is very bizarre.
Coco and peat stuff is already kinda on the acid filler side. And while I don't have an issue with lemon juice really (coz of ascorbic and citric acid), that's also acidic...
I would seriously give that thing a good helping of calcium, potassium, some magnesium and a carbon food source.
