Cream Cookies Fast Buds -1st Auto Grow

Started LST 5 days ago, so they are staying short. They are flowering up a bit too. Haven't had any real issues. They seems to wilt when I water them, but they are perked back up in a few hours. The lady in the back is not getting LST. She started off rough and I was actually worried she wasn't going to make it in the beginning. I'm still watering with tap water PH'd to 6.3 except for the runt in the back. I decided to make her my guinea pig. I gave her 1/2 dose of GH Flora trio today. The FFOF soil seems to be doing its job so far in all of them, but I figured I would try feeding it different nutes than what is in my water. My tap water is at 260ppm, so when I fed the runt, I used distilled water, and after adding GH nutes, ppm was 270. So, pretty much replaced only tap water nutes with only GH nutes. I will up ppm every other feeding just to make sure I don't over do it with them being in FFOF. Run off water is at 650ppm on all plants right now. I have another tent setup if these gals fill the space and it gets to crowded.
