Purple stems, some droopy leaves, pics

[VeoDigital]

45 days old, one is sexed female for sure, and I think one is male =( , others unknown.
Transplanted three days ago, Flushed soil before transplanting and let drain for an hour.
Five are in 14" 5 gallon pots, three in 10" 2.5 gallon pots, three biggest were root bound others were getting there.
Lights: 1 x 400w mh (4000k), 4 x 42w cfl (2700k) 18/6 schedule.
Medium: Promix
Nutes: Foxfarm grow big 6-4-4.
Stems of fan leaves on all are purple, and some purple showing on main stalks (phosphorus deficiency?).
Each plant has fan leaves drooping, showing some nitrogen toxicity claw action, needs a flush?
Looks to be a little nute burn on two by the browning/yellowing of lower fan leaves.
Had an early ph issue, which I think I corrected (still no soil ph meter, I know BAD - Short on cash).
Soil is still very moist from original transplant, should I flush or wait for it to dry up a bit?
If it is a phosphorus def, should I sprinkle guano on surface and flush? or feed something like Buddswell?
Ill let pics speak for themselves, any help is greatly appreciated. Need any other info from me feel free to ask!
Edit: I know they are short, stunted from root bound and early ph issue. Secondly, I know the pots could have more soil in them, but again was short on cash and couldnt see purchasing another 4 cu ft of promix for such a little need. I will add soil later to the bottom when I begin clone box.

overall they look pretty good to me with the exception of the droop which I believe is overwatering

Pic #1 is the female, which has started to show the purple stems, could be genetics, but all the plants have developed it. Im glad I have "The Man's" approval, was hoping you would responed. Your like the seasoned Doctor in the ER everyone goes too, lol. Do they seem stunted GG? Looked at them this morning after their sleep, and the droop is gone in all but one. Maybe Im paranoid about the wrong things.
