This goddamn leaf problem is back (CFL)

Hey yall, Im growing with CFL's, this is my third time around. My previous grows have been learning experiences as is this one, a little more serious this time though.

My last grow I had this problem that I thought might have been overwatering, but as I leanred proper ways to water and when and how much....I know im not overwatering.

PROBLEM: LEAF CURL DOWNWARD, slight burn (I can take care of that), unusually light green new growth

She was vegged for about a month and a half and is currently 16 days since first pistil.

MEDIUM: Fox Farm Ocean Forest w/ a very small amount of MG organic potting soil mixed in (after I started the transplant I realized I didnt have enough FFOF) DOH!
Fed every other watering with Tiger Bloom at 2 tsp/gal, and has been fed once with molasses.

is high heat/ low humidity my problem??!!?!?
stays between 75 and 85, and humidity around 35%

PICS: (tried to take them with various different light)

Have you changed lighting and have temps gone up?

Okay okay so maybe phosphorus abundance, but I haven't fed it tiger bloom in so long. I added one bulb probably 2 weeks ago, didnt really raise temps too much. Is it just looking like heat stress?

Yes it does ,some strains go lime coloured in the tips at the beginning of flowering but this is worse.
