HELP 3 ladies in danger :(

I currently have 3 ladies at home with me, and 1 is starting to become YELLOW. While they all are continuing to FLOURISH, I can't get the yellowness out of my strawberry cough.
I only recently (5 days prior to posting) started using a veg bloom nutrient, Iguana Grow Juice. New growth continues to show daily and plants show no sign of stuned growth or wilted leaves. The Cough is just shy of 2 mos old, taken from a clone at 3 weeks. I run a 600w superHPS with a gorilla grow dual buld vented hood.
My guess along with other friends it a N lockout. Any quick fix's? I'm really trying not to flush my soil. I've always been accurate when adding my water and neuts (always water with a 6.2 pH)
Anything would be appreciated, sorry There's no pics up, will come shortly.:thumbsup:

welcome to the boards!

fill out the troubleshooting form (in my sig) and post in the plant problems sub-forum.

hurry up with those pics already.

6.2 is a smidge low. 6.3 is what most growers in dirt aim for (not that this is the root of your problem).

nitrogen is a mobile element, so if it was needed in certain areas of a plant it will be moved from other areas although it is slower to old leaves.

any diagnosis here and now would be premature and shotgunned at best. shotgun troubleshooting is when you aim at your troubleshooting flow chart and fire off a buckshot shell at it and pick a place hit by a BB and start. most around here are not into wasting time or risking someone elses meds with bad advice.

the 1st pic is the overall look of my mother cough. I actually had to take it out of the room, because the hps light made ALL leaves look yellow. lol... And iPhones take the worlds BEST pics. ha, right...
Anyways... she has been tied down in over 5 different places, that explaining why it lays horizontal. Now instead of 1 head, I have 5. :)
The 2nd pic is a close up of sum rust colored pigment on some lower foilage.
I am getting new batteries and looking for my damn USB cord to upload better imaged pics. Let me know what you think. Ty:thumbsup:
