Oooh,
This is definitely fixable. You have 2 issues that I can see in addition to whats been mentioned. Your PH seems to be too high. My guess is around 8. You should flush the black gold with ph'd water to calm down the nutes a bit and to lower your ph before you pot your seedlings.
You also need more perlite. These little guys are a bit young to replant so fast. I like to keep em in 4" squares or 16 oz plastic cups for the first few weeks before transplanting them. The fail safe method of mine is to use a soiless nutrient free mix for the first stage, then pot into a soil that has my nutes. Just remember, although is says 6 months, you will still need to add some organic nutes for higher yields in the later stages.
ALSO: Run down to your local garden shop and ask for a nursery flat. The flat will catch all the run off which you can use to test the PH. They usually give the away for free. If not there only 99 cents. Also, you can get some small square pots for around 20 cents and regular 1 gal to 3 gal nursery pots for around 67 cents.
The problem here is that you need to correct your ph without over watering the little guys (hopefully not guys, sry). Then you need to test your run off to see if that is the issue. The towel has to go and for proper drainage, you will need five half inch holes in those containers.
