Somethings just not right! Need Recs!!

Total rookie and need some advice. Plants are about 1 month old. Ebb and Flow system. Temps about 85 and humidity 45 percent. 600 w HPS on 18 and 6 (i know i need a MH). Squirrel cage fan turn the room around 5 times a min. PH is around 5.8. The plants are growing but not thriving First my concern is over watering?? The plant seem to be drooping. My watering schedule is 15 min ever two hours. With the timer i have it runs for 15 and about another 10 for drain. 25min every two hours. Day and night. Is this right? I started in rock wool 1 inch and transfered to the clay balls.
Next is Nutes, I have AN Grow Micro Bloom. I am using it 1-1-1 to keep it easy> problem is i am being told two different things from AN and from my local shop The shop is telling me 300-600-900-1200 for veg. AN is telling me in the EBB and flow to use 60 percent of that value. My shop says they are crazy. any recs? Please weigh in.
thx!!

These are very similar to what my plants look like atm besides the overwatering part, very interested to see what the outcome is, im thinking it could possibly be heat stress, but not exactly sure.

well for starters no three part is meant to be used 1-1-1. They must have a three part feed schedule somewhere. I hear the lucas works with AN. Try 8 ml micro and 16 ml bloom per gallon.

oh and I looked at the pics. you have nute burn and heat prob. also what is your water schedule and pot size.

Over watering looks to me.
