Light Bleaching?

[Scias13]

1.) I fell asleep with my plant like 1.5 inches away from 3 cfl lights which usually cause my enclosure to get to about 100 degrees. When I woke up... the first set of fan leaves looked like this. I have the humidity up at about 30%, the soil PH is 6.0 (im watering with filtered plain water once a day when the soil is dry). Is this a case of bleaching? Under/over watering? Nute Deficiency(havent given any nutes yet... its about 2 weeks old)? Theother 8 of the little sprouting fan leaves seem to be ok though.

2.) No matter how close, or far for that matter, I seem to place my plant from my lights they seem to keep pointing straight upwards, any ideas on why?

was the plant transplanted at all like from a starter block to soil or was it sprouted in that cup? sometimes when i transplant i get a little yellowing
it doesnt look too bad because the leaves arent showing signs of dying yet but move the lights up and watch the new growth because thatll show you if your doing something wrong.
hopefully someone else chimes in as im not to sure

I think it could possibly be nitrogen deficiency since the yellowing started at the tip?
I did transplant it from a spongepot to the pot in the picture. My leaves seem kinda small for two weeks im thinking? Maybe my pot is too deep and the roots keep growing down so its using most its energy for root growth and the leaves aren't getting enough love for the amount of light on them?

Look out for those lower leafs. If yellowing continues (spreads on those leafs moving towards the stem and to the upper leaves), then you might have a N deficiency. But judging by the size of the seedling, I wouldn't bet on it. Heat might be as well an issue, the temps are kind of out of the charts. Need to lower the temp a good 10+ degrees.

But, there are other factors as well. What soil is that? Like asked before, did you transplant yet? The new soil might be too strong in fertilizers, let us know what you're using (soil, not fert. you shouldn't be using any fertilizers on them for at least the following 2 weeks). If the yellowing stopped, and as I see the new growth doesn't show signs of it, you might be out of the radar for now.

Watering once a day is waaay more than these little ones can handle. Water until water comes out of the bottom and when it starts to do so, stop. Also, don't flood the main stem. Now, given your high temps, a watering every 2 days might be necessary, maybe even 3, depends on how fast the soil dries.

Keep your CFLs at about 2-3 inches, but I would advise a fan or an air extractor to lower the temps, they seem very high to me, especially if you have an indica. Air flow is just as important as lights, as I have found out on my own just a short while ago.

I did transplant it into osmocote plant soil with smart release plant food. I have it at about a 65/35 blend with perlite. So far when watering i don't even water it to the point of run off and I only water when the soil looks extremely dry (i have a water meter thingy too) and my soil always seems to be on the dry side. As for venting I have 2 8mm cpu fans going but it still seems to get really hot in there not sure what else i can do. Its mainly from my bigger 2700k CFL that causes the over heating. As of right now all of the other leaves look normal its just the bottom rounded leaves (they died completely) and the first set of fan leaves that yellowed. Also, I've got the temp down to 87ºF by switchin gout the bigger CFL.

Too much water.

No u can have fluros that close. The biggest problem is the 100 deg in there(strange that its that hot with only cfls), you will have to get this down to max 80 to get best results. Get an exhaust fan and osc fan in there.

Heres a pic from today... I replanted it in a different(smaller pot to get a better root structure hopefully) and exchanged the hot 50 watt 2700k with a 20 watt one to reduce the temps down to the mid 80 range. She seemed to take to it and growth seemed to spurt a bit
