My Poorly Auto White Russian

Hi, Im looking for some advice on my poorly Automatic White Russian, who's called X. I know I dont have ideal conditions but I have done one grow of Lowryder very successfully with the same set-up. Personally I cant see any difference apart from the cold and it being a different strain.

Im using Miracle Grow soil (yea I know shoot me now. Its the only stuff my local has. Worked with the LRs tho. Used the normal stuff to start with but repotted her with the organic MG which isnt quite as strong on nutes. But it cant be lack of nutes in the soil coz she hasnt been in this new soil long enough to use all the nutes in it!)
I have 3 big CFLs, 2 duals but X is under the red side of a 125w one.
She hasnt had any nutes
Her leaves have been going pale and patchy for a while but now she just looks like shes dying.
Her stem has been purple for a while and the purple is spreading.
The lights used to be on 19/5 but it got very cold in the dark and I thought the cold was the problem so just under a week ago I started keeping one of the lights on 24/0 to keep it warm. I should maybe mention that this is an automatic variety that automatically flowers after 3 weeks regardless of the light regime (can be grown all the way under 24/0).
Last night I gave her a real good flush so Im hoping that will help but if anyone thinks theres anything else I can do? Also, I have no money so if the solution could be free that would be great!
I have no fan, no pH tester and no thermometer which I know is a b*tch but I was hoping some expert out there could spot the problem regardless. Heres hoping...

Thanks in advance to anyone willing to help!

looks like nitrogen deficency, or mayb. least likeyl of the 2 but mayb calcium deficeny. the one leaf with the burns between the veins on the leaf make it look like it....

no offense but this is what happens when using miracle grow soil designed for heavy bearing fruits and vegatbles-nute blasting and off balance ph locking out nutes.
I would feed her any nutes for anytime soon and can only recomend that you obtain some fine dolomite lime from home depot and add nice layer on top of soil-this will act as a strong ph buffer and privde your gals with the micro nutrients she is missing like MG, from what I can see

ive used mg orgainic with much success before. it could be perhaps it was the transplant from the regular mg soil to the organic. have you been feeding it extra? it does look like nute burn. anyway its dosent look that bad, just give her time. maybe another flush if it gets worse, besides that leave it be. if it gets worse post another pic.

Personally, I dont think it can be defficiency in that the nutes arnt there for it as they have been repotted into fresh nute filled soil. I dont think its nute burn at all either because the leaves arnt curling and just the apearance of them says defficiency - they just look like theyre not getting what they need to build themselves and keep themselves going. This brings me to the conclusion that it is something stopping them from absorbing the nutes. Ive heard that cold and pH can do this. Well I think Ive solved the cold problem and Im hoping the flushing will help the pH get back to normal. Ive just watered with some calcified seaweed to help the pH and give them calcium and minerals and other nice crap thats in there. I dont know what else to do.

again, fine dolomite lime will proved a nice ph buffer along with all the micro nutrients she needs, mg, zn, cu, fe, ca. I mean those pics clearly represnt an advancing stage of mg deficiency. notice the dark green veins along with yellow interveinal banding? just b/c there are nutes in the soil doesnt mean she cant get a deficiency. are you ph'ing your water and montioring your runoff?

in either case queen bee id leave it alone for a while. good luck.

the lime can only help and almost zero chance of burning her.

Ive never seen dolomite lime except for in pebble form for decoration. Thats why I went with the calcified seaweed - it was the best alternative I could find - will that help? Im going to try find some dolomite lime asap

I admit I am not up to date on what the calcium seaweed has, it may have the same as lime. you can pick up lime at home depot or any gardening/hardware store. If you feel she has the nutes she needs than it is just a ph issue which the lime will help you correct and maintain. $2.00 for 40lb bag I believe.
