Seedling Curling Down Pics Included

I have four seedlings that are about 4-7 days old. Two of the seedlings look fine and the other two have leaves that are curling down. What does it look like the problem is?

My temps is 80 Degrees
Humidity about 35%
Using Sunshine Mix 4
Watered with ph water 6.0
I put 3 drops of General Hydroponics rapid start in a gallon jug 20131219_043202.jpg20131219_043212.jpg20131219_043218.jpg

as ^^ i wouldn't use the rock wool in soil. plants normally grow in just soil. some things have a better chance at living then others. three of the four look pretty good

not a good idea to put seedlings in pre-ferted soil, they could burn. they need zero nutes for the first couple weeks. the rock-wool cubes aren't a big deal. as soon as the roots grow through into the soil, they're fine. you don't need the hydroton either. soil ph is 6.5.....

Shouldn't be using rockwool cubes in soil. They retain far too much moisture. I believe your over-complicating the sprouting process. Its as easy as germinating a seed, planting it, and letting it grow, no need for the extras.
