Each strain is going to like a certain blend of nutrients in a way that is totally unique to its genetics.
Keep your humidity dialed in, and your temperatures controlled also. Humidity affects Cannabis flowering in very strange ways. Stunting flower production occurred in my first grow with humidity levels around 70 percent. I found the sweet spot to be around 45-50 with lights on, and 60-65 lights off.
Nitrozyme is the shizzle during veg! Once a week, I applied a half strength shot of Nitrozyme, it really boosts a plants veg production based on what phase of vegging its in...ie tilling stage, stalk growth, root growth, etc. When they were clones I applied the Nitrozyme as a tank feed for their first and second watering, then it was foliar from then on.
Any specific questions?
