Hey guys I currently don't have a camera or even a camera phone so I can't provide pictures which I know will make this difficult. I have 3 plants, started as seeds in rockwool two weeks ago. I transplanted them two days ago after their roots started poking out of the bottom of the rockwool (also they looked fine at the time of transplant, rockwool was ph'd to 5.5 before they were planted into them). I transplanted into a mix of Fox Farms Ocean Forest and perlite/vermiculite. The ratio for the soil was 80% FFOF and 20% perlite/vermiculite mix. I also added Mykos myco innoculant to the soil right where the rockwool would be so the roots would contact as they stretched out of the cube into the soil. I also switched over to a 600W MH that rests about 15" from the tips of the plants. Room temps have been about a constant 87F and RH has been about 50-60%. I gave the new pots a good watering of distilled (ph tested to 5.8) water after transplanting and haven't touched them with water in the last two days. So one of the little ones looks wilted and basically dying, no spots of any kind, and it still has a nice deep green coloration. The other two have developed brown spots around the leaves, and brownish looking tips. What's strange is the first set of leaves(real not cotyledons) have started to droop down at the tips, while the second set of real leaves have started to curl upwards at the edges like tacos. Please help!

Bring your PH up. 5.0 is too low for soil, try and get somewhere between 6.2-6.9 or somewhere there.
Try 1 tbsp dolomite lime / gallon of water.

A seedling does not need 600w and especially not that close. Raise the light or even switch to cfl's for a week or so. Put some kind of dome over them to raise your rh for a few days. Your mix is pretty hot for a seedling as well. FFOF is notoriously hot and should be well buffered. Also the soil has everything and then some that a seedling needs. Additives of any kind are superfluous and potentially harmful. Good Luck to you.

Soil is hot, lights too close and ph is low. Using hot soil on young plants got me in the past. I'd start with the light 2' over em if cooled. Get the ph up to 6.5.
