I keep the lights rotated between 8-10" to 20-24". The last day and a half they have been at about 18" though. Again CFL. So low heat on the plants.

Mind you, the other 3 plants are tolerating very well.
Wondering if she might be nute sensitive?
Maybe I should flush her today? (It's feed day)

Some can't handle the heat, others can. Looks like heat stress.

It gets warm in the tent, maybe that's it. I'll try to drop the temp a few degrees. I went a head and did a water only feed today. Hoping she'll feel better in a couple days. Thanks for the help.

... temps are a bit high, RH is OK, but not much higher for those temps,... symptoms are definitely env. related, not nutritional that I can tell, so no flushing! I'm with Star' on this, likely it's touchy strain/pheno, as not ther symptoms seem present, and the other plants are fine,... was this one getting blasted by the fans? Any combination of higher temps, very low or high RH, and strong breezes can bring on these symptoms,... see if some cooling and shuffling helps, along with checking on how strongly the air is moving against the plants,......really low RH puts a huge draw demand on water up to the leaves to cool them (transpiration) and stay hydrated properly; high RH badly retards transpiration because of low evaporation rates, slowing movement of nutrients from roots up,... in the former, strong breezes will worsen things, the latter, improve them some,...

Very helpful, and spot on. The first 2 weeks humidity was very low, probably 25 - 30% and the fan was very close to her. I've got the tent at 82F now and RH is about 48%. She looks a little better this a.m..
