Royal Seed Critical Hydro First Grow

Seeds germed in moist paper towel placed in sealable container and placed in back of kitchen cabinet dark location. Fully sprouted 3 days after. Seeds placed in rockwool blocks in (3) 5 gallon bucket setup surrounded by hydroton for growing medium. Each bucket has small pump, air pump and 4 cap fulls of each (2) nutes. I’m testing rather the spray nozzle is better or continuous flow. Better pics will follow I know the grow light pics suck.
