GDP x AK47 RDWC lil bit of drooping and brown spotting

Cant tell whats going on but my ak47 x gdp babies have been in veg 4 about 4 days now and i've been running a big dog 12 lamp T5 24 hours about 24 inches from the top im running sensi a and b grow pirahna tarantula carboload and sensizym. my ppms are around 450 in a rdwc current culture 8 site system im just curious as to what the plants are doing and why they are reacting the way they are this is my first grow so i am not good at diagnosing problems any help would be greatly appreciated.

check your PH. keep it at 6....

i've been keep it ph at 5.7-6.0 because of ph fluctuations goin up im constantly having to add lil bits of ph down. my room temps are 75 humidity is 45% and res temps are 69-70. i just lowered my res levels because i felt they were getting a lil high and the rockwool might have been getting flooded. im hoping that lowering it will make my roots search a lil more. i havent seen any sign of roots poking through the clay pebs yet

huh, i was going to say pH too as that always seems to be the thing that messes my grows up.

i would also like to point out that it seems like you're running a lot of nutes in this systems

for a first grow, that seems like it might be a lot ot handle all at once...

i mean, i like AN nutes, but even I couldn't handle that complciated of a schedule when i was first starting out...
