slow dark green new growth/ yellowing leaves dying older growth

Growing in coco/ perlite
PH is 5.5 but runoff is 6.0 or 6.2
6x 23w CFL's a 65w cfl and 2x 125w cfl mixed warm and daylight
Put sprouted seeds in coco on 5/18/13 so just over 3 weeks old.
Was Using botanic are pure blend pro bloom 2-3-5 (I know) at 10mg / gal but just flushed with 15mg / gal Phed to 5.5. I had been mixing a gallon and it would last 3-4 days so I'm wondering if leaving the solution uncovered might have messed with the nutrients... the pH of the solution stayed the same though.

Trying to figure out how to attach a pic. Will upload to photo bucket if I can't did to this post cuz I'm on my phone

Welcome, the odds of getting people to help depend greatly on pictures you post directly. 1st ph to 5.8. Also, 3 weeks is pretty young for nutrients beyond 1/4 strength.

It wouldn't let me post a pic cuz I was so new but its up now and thanks glad to be here.
