Yo man if you look at my previous grow you will see I've been there. Your suppose to add epsom salt at day 21 of flower 1tbl spoon per 10l (dissolved) and I'd recommend using biobizz heaven also. Expensive but that's why. Seems like your using too much grow for week 3 of flower. I also use half grow half fishmix works a treat. Don't stress man even if it carry's on you'll get a crop out if it
