IMHO all you have to do is stay meticulous, read and read some more my plants gets 3-5 hrs of my time daily. The first time I notice anything I’ll change res in a new york minute. I use Armor Si 1.5 ml, Cali magic 4.5 ml, fl micro 12 ml, 15 ml of flora gro, 3 ml of fl bloom, 7 ml rapid, 3 ml floralicious plus, Dia nectar 15 ml, Flora blend 15 ml. I’m flipping in a few weeks then switching to soil. That’s where I fear i’ll have problems . Hydro seems easier too me. I don’t fear flowering I spend 3-5 hrs daily watching, and studying my babies. A friend said go with soil there pulling according to him 11+ lbs off like 9 1000watt hps. His exact words were: My plants are as big as Shaq! Says my plants aren’t a good size considering there about 8 wks old. I struggled with humidity, I didn’t want to buy a commercial humidifier just yet. Winter humidity is brutal. I did buy a reptile fogger it works great next Veg i’m going to use two with a thermostat to control everything better.
