Initially, fertilization was 10ml grow 5ml Bloom 5ml micro, 10ml enzymes, 2ml rootbastic and 10ml liquid oxygen/10 liters. When I was worried and suspected that there might be too little nitrogen for a lighter plant, I added full fertilizers (Advanced Hydrophonics of Holland) 20ml grow, 10ml bloom, 10ml micro and 10ml enzymes 2mlrootbastic, but as the situation got worse I changed to 2.5ml grow 2.5ml Bloom 2.5mlmicro and enzymes 10ml and liquid oxygen 10ml per 10l of water after a day. In addition, I sprayed off all possible residues with a shower.
