@rodri59, I don’t think citric acid is a bad thing if you use the water right away. In fact: the ph rising can be taken advantage of and one could say, ph for a water-only watering in soil, ph down to 6.0 from say 7.0 with citric acid and as the ph goes up over time, different nutrients reach peak solubility.
I’ve been using it in my grows with excellent results but it’s not stable for storage and it almost bit me where the led’s don’t shine haha.
Don’t give up on the Gold Leaf! It’s a ridiculously vigorous plant. I have one 3 weeks in flower now. She’s telling everyone ELSE what to do lol.
