Help needed by seasoned pro.

I got a 30 pack of Fire OG clones by DarkHeart nursery from a friend. When I got them they looked dark green and had wilted, twisted leaves. I was pretty sure they didnt rinse the rockwool and got them PH locked. Planted them in my Ebb and Grow system under 4K watts, filled my 55 gallon res, PH'd to 5.5, and began to top water them to flush rockwool. Cleaned res, re-filled, added 12mil per gallon DM Zone, 5mil per gallon Florakleen, and ph'd to 5.5. Ran this setup for 4 days. Plants picked up a little bit so i waited 1 more day, drained res, re-filled with seedling strength GH nutes and 5mil per gallon DM Zone. NOTHING is changing, no groth, not perking up the way they should...oh yeah, its has been 2 weeks now. Lights are on 18 and watering 3 times .

FYI, i have tried to play with water cycle to be sure im not overwatering; not the case.

plants need a little stretching, your lights are a little too close. try taking pics in white light next time, not sodium. try pH at 5.8 to 6.2. I think 5.5 is too low. I can't see your pics in an enlarged format for some unknown reason, but it looks like there might be yellowing of the outer part of the leaves. make sure that the ferts you use have everything plants need. there's about 16 different nutes altogether, but read the labels, do some research on what plants require, and only buy the products that give the biggest value for the money, like Dynagrow, which is good in both soil and hydro.

Actually PH 5.5 is about right for your setup.
And the nutes are fine.

I would try raising the lights a bit.
Just like water, and nutes, more than enough, is too much.

Looking at that hydrotron, I'll bet a nickle that you PH does not stay at 5.5 for long.
Humor me, measure it and get back to us.
