6-12/gal might be about right for LED lighting, you can try 7/14 next time if you want to try to push them a bit but if you see signs of problems, just cut back to 6-12.

Update, it's been almost two weeks since my last post. There has been significant growth as you will soon see. The four plants are drinking approximately 1 gal a day. My two h.s. Plants are almost 10 inches tall and will be super cropped soon. I took a cutting today and it will be entering a 24 hour dark period and then straight to 12/12 to sex the h.s. , it is now in a glass of the brew from my E.G. Ph is a stable 5.7 now it's jusst a wait to find out.
Room temp: 72 vent on 78 vent off Res temp: 67.2 Ph: 5.7 Res change: 1/28/14 New res nutes: 70/140 GH flora micro/flora bloom 10 gal R.O. 10 ml GH ph up
Looks like one of the hs1 plants might need a little cal-mag or epsom salts...but they all still look pretty good.

The four plants are drinking a gal of fluid a day, I will be flipping to 12/12 on valentines day after another res change the way things are going. There are so many roots when I changed the fluid out it was hard to hold them up. I did some super cropping and removed a few clones. I also grabbed the top of my last living red dragon. I'm hoping for the best. I put them into my aero cloning bucket with 2 gal r.o. .5 ml rapid start and a sample of extreme azos. Ph is 5.8 and temp is 65
SME when using florakleen am I supposed to add it to the old nute solution and let it run? Or am I supposed to drain refill with fresh water and florakleen then let it run drain again and refill with a new nute solution?
for the florakleen, just follow the recipe on the bottle. there are 2 flushes: a "normal" and final. the normal is during the grow and you are right. drain, refill with RO and florakleen and run for a few hours only. then drain and refill with new nute solution.
to see what it does, right after you add the FK and RO measure your EC/ppm. after the few hours of flushing, you should see the EC/ppm go up as the salts are removed from the plants.
I do see some burnt tips but I don't know if it's new or old damage. They look pretty healthy other than that and that's minor.

A lot of the undergrowth was being hidden from the light on the H.S. Plants the leaves were soft and didn't unfold properly... and they have gotten kinda cold a few nights with our temps outside being below 20 degrees outside but never below 66 and res temp is pretty stable at or around 65
