Shouldnt be a problem, they are pretty hardy plants, Put your hand above the plants, if you can feel the heat on the back of your hand the plants will feel it also. raise the lights about 2"-3" above the plants, cfl lights dont get as hot as hps. at such an early stage you dont really need to spray the leaves, this is genrally done when they are a bit bigger. when the leaves are wet sometimes the lights can act like little magnifiying glasses if the lights are to close. Hope this helps

in that pic they look fine just keep letting them be the only time ive had serious burns are when my cfls fell.... if theyre not yellowing or brown dont worry just let it be all that is really important is the growing temp at this point

Back in the day I grew with CFL's. From experience I can tell you that you do not need to have the bulb within 1 inch of the foliage. Everyone is hung up on proximity with CFL's and they think that if it's more than 2 inches away from the foliage that it loses it's efficacy. I can tell you that you can keep those CFL's 4 inches away from the tops and you won't lose anything. That will eliminate a little of the heat but you really need to keep your veg area between 70 and 78 degrees if at all possible. 86 is too hot and it will stress your plants which will hurt your yield. Make sure you bring the temps down a little. However, the seedlings in the picture that you posted all look fine.

true but proximity is based on bulb size small bulbs should be farther 23 need to be about 2 in away 42 can be 4in away

your welcome if you stretch its from the warm white not proximity. but 1 42 6500k is strong enough for those two untill they fatten up so i wouldnt worry about stretching

so what will happen with the burn marks will those leafs will forever be nuked or will they heal in time?
ill post another picture in the morning i might be paranoid but it looks like its getting worse but i think a 12 hour comparison will tell me much more about them but they look worse than better for sure... and i was so proud

well the burns wont repair but the bottom set usually falls of any way so its okay youll only have one set of burnt leaves

what is your intake and exhaust like? how is your growbox/room setup? 86 is pretty hot, you mos def don;t want it any hotter, but if you can keep it around 80, that is perfect!
