You have to keep giving them the growbig, it's readily available so it's used up very quickly... I would supplement every feeding with at least 1 ts of growbig if not more
My plants are still looking bad, and getting worse. My pineapple express is getting yellow, and the rest are degrading. I fed them 3 tsp of grow big and 2 tsp of tiger bloom.
How often are you feeding them? How are you feeding them? What type of water (i.e. tap, well, or RO). More information would help in determining your issue.
Looks just like my girls did when I first switched to RO. Didn't know that you needed cal mag. I have been adding cal mag with every watering now and have not had an issue since.
