I get the feeling it might be a little nitrogen deficiency, what kind of soil is that and are you feeding it any nutes or just water? what size are those lights? what rating. 6500K or what?
i have 2 23 watt and a 26 watt cfl on her there the big bulbs. lumens are at 4900 and k is at 9500 which might be too much im using hyponex soil no nutes the only thing i got is mg and ppl say to stay away from mg... its liquid drops.
not sure on the temp as i have a fan blowing on her as well. the soil is hypnoex with no nutes. and im doing a cabinet cfl grow. using 2 23 watt cfls and a single 26 watt cfl bulb.
Take away one of those bulbs and give it a lot of water tonight & make sure it runs out of the bottom for a little(30 seconds most).
Put some stone's on the bottom of the pot so the holes & roots get more oxygen & it drains better.
