keep a plant of each in veg if you can, or just send them to me i have 4 400's over 9 plants, still not enough. as for watering and nutes, grow big is pretty strong shit, i only use 1tsp every other watering with a about a tbs of big bloom.
I dont use fox farm nutes like i said earlier, but most nutrients are applied per gallon so i believe Itsus is talking about adding both of those to 1 gallon of water. Also never add nutrients to nutrients always add each to water. NEVER MIX NUTRIENTS TOGETHER BEFORE ADDING TO WATER( if you need more calrification ask).
