They should definitely have that as well.

I'm no soil pro....hence the link to problems for soil growers....to me the issue seems to be either ph or too much nutes for seedlings. It just doesn't LOOK like a heat issue....but then seedlings can do funny things. Also....which three are we talking about.......the three closest to the light? If its heat you should see it in a clear pattern from the closet plants outward.

I'm afraid that is all I can offer you here so feel free to take my advice with a grain of salt.....as I said soil is NOT my strong point.....at all.
No your help is well welcomed. You know a worldly amount more about this than I do so I appreciate your input. If nothing else it gives me something to bounce ideas off of. I have pictures of the setup in my grow log but I'll post some here as well.

Previously the pots were probably about 1" away from my CFL's. Here's a quick rundown of my setup.

1 cardboard box 23"x23"x30"
Lined with Mylar inside.
1 19" box fan for the exhaust, set on low.
1 3 speed oscillating fan set in a fixed position also set on low.
12 CFL's:
4 60watt Equivelant CFLs
8 100 watt Equivelant CFL's
Total Lumen output = approx 14k (inside of a 2'x2' area).
Light schedule is 18/6, was 24/0 before.

Thermometer/hygrometer reads usually about 77 degrees and 35-37% humidity.

For PH testing I use an actual digital meter.

For nutes (which I don't use yet) I have a soil kit but looking for something to give me a better/more accurate read out of NPK.

All plants were pretty much equally distanced from the light.

I've since lowered the plants 4" away from the light. I'm hoping this resolves my problem.

The one plant with the mega super ultra retarded curled leaf looks to be doing a little better after only a couple of hours. It's second set of leaves are slowly coming back down.

The picture is my grow box before I lowered the plants. For reference those lights are about 1", maybe a little over away from the plants. I would say no more than 1.5"

I've since gone ahead and moved the plants to 4" away from the lights.
daihashi Reviewed by daihashi on . 77-80 Degrees w/ 35% humidity. Possible heat problem? I have a few plants that are exhibiting some problems while others are doing just fine. These plants are only about 7 days old. My soil has no nutes and PH is around 7.0PH. I water this with water PH'd to 5.9 and the runoff comes out to be between 6.3 and 6.6. I only water twice a week, trying to get 3-4 days in between. I germinated these seedlings in paper towels and then placed them in rapid rooters before placing them in their semi permanent homes.
