New leaves are curling?

PC Grow
2xCFL 24watt
Leaves started curling when I gave them some organic seaweed extract at about day 8 from seed
Ever since the leaves have little yellow spots, some are cut open :/

Anyway these new leaves are curling heaps and i'm not sure

notes: I have a PC fan blowing on it 2 cm away from the plant
2 exhaust
Lights are pointed down and about

if they have been doing that since 8 days then thats been a while cuz those are nowhere near 8 days....heres what id do - repot them in some good soil, no delay release crap no miracle gro..then you need to stick to a watering cycle they look over or under watered...you water when the top couple inches of soil is getting dry then you dont water until this happens again, you may wind up watering 2 times a week or so and you need to feed them once a week. you should never add or feed anything at 8 days btw, just let them go until they are about the size you have now before you need to feed them but ofcourse this info is based on you using soil that is decent and already has a little nutrients within it...so recap, repot in good soil then water once with nutes (if your new to this grab the technaflora starter kit or the general organics go box for organics) follow the easy to use chart on the box also only water with distilled water or water that has sat out for 2 days...by the time its time to water again with normal water you should see some improvement

repot into 5 gallons at least...

Looks like a Calcium Deficiency! Anything below a PH of 6.5 in soil locks out Calcium. Anything above 6.5 unlocks Calcium.

severe overwatering

Yes its overwatering, and your finger print is so clear that i hope your not on file.
