I use GH MaxiGrow and MaxiBloom (Dry Nutrients), Sweet Nectar and KoolBloom (liquid nutrients). During veg, I basically hand feed them in the rockwool until they get big enough to go into my Ebb & Flow setup. I mix up some nutes in a bucket, for a week, and feed once a day. Mix up 1 Gallon of water with 1/4 tsp. MaxiGrow, and 1 tsp. S. Nectar (PH 5.5). Then after a month, they go into the ebb & flow. My resevoir is 8 gallons, and I start off low and work my way up in nute strength. Start off with 3 tsp. MaxiBloom, 1 1/2 tsp. MaxiGrow, and 3 tsp. S. Nectar (PH 5.5). Then gradually go up while keeping the ratio the same: 4 tsp. MaxiBloom, 2 tsp. MaxiGrow, 3 tsp. S. Nectar (PH 5.5). After 3-5 weeks,stop feeding with MaxiGrow, and replace it with KoolBloom while keeping the ratio the same. The last 2-3 weeks, I cut my nutrient strength in half, and add some Gravity (Humbolt County's Own), or you could use some unsulfured molasses with plain water. That's it, I hope this helps.
