first grow meds day 17 of veg haveing some problems. (pic)

im growing blue cheese (big budha x Blueberry) clones. they are on day 17 and have been vegging under a 400watt MH + 6 24watt CFLS . this is there first day of vegging under my new T5 8 tube florecent fixture.over the past few days most of the stems have been turning dark purple. and seems to have slightly stunted growth as well as whats shown in the following picture. If anyone can offer any kind of help it would much very much appreciated.

What are your temps... also looks like you are using LED throw that crap awat MH & HPS are the best, you will not get the results you want with LED. Ok back to your plant what type of soil are you using and ph water and how much nutes ... Thanks!!

the temps stay close to 80 im using local soil called m3 mix 'medical marijuana mix' can be found at www.jfmmm.com. the first watering i didnt have a ph meter but found it was a PH of 7 after i got the meter for the 2nd watering I PH'd it to 6(recommended on mix) . I have only fed them once with a 1/4 dose of Dyna-Gro foliage pro(9-3-6).

i think i need to change my PH to 6.55 and give them a good feeding 5ml dynagro foliage pro(9-3-6) ??

Yes at 6.5 your plants cn absorb the nutes better,mayby some cal-mag would help.

what about all of the purple.? nitrogen def.?
i have foliar fed them with cal mag+ . hoping the high N from the foliage pro will help.
