Thank you everyone! I did not feed it too much, just 1ml of bio grow on 1 l of water, but i used their all mix which is heavly fertilized as far as I know. Ph runoff was 6.5 maybe a bit too high? Changing formulas... i'm not at that level. Did order a calmag to see if that does anything. As for water i tried to do dry/wet periods 1 plant got about 1 liter of water every 3 days, I was adding bio grow feed as instructed.
