First flood and drain, First synthetics run

Ok, here pictures of my first flood and drain/synthetics run. I have always used no till until today. I have 4 different pheno's of my gg4 from sure bred seeds off of strainly. I have them in pure coco. I originally set it to flood 2 times per day every day, all week but thinking abt it and looking at the coco I've reset it to 1 time a day every other day for at least the first 2 weeks.

I am using:
AN bloom A&B
Voodoo juice
Bud Candy
Gen.Org. Cal Mag.

My PPM's are 360
PH 6.0
600 WATT SOLIS TEK XXXL hood set at 400 watt during this 1st and only week of veg.

This sucked. Ea plant grew 1 nice nug, not really even a big one. Switching to hand feed bigger plants. Maybe drip system.
