Leaves curling upward

Hey guys,
I've thumbed through the guides to figure out why the leaves on my plants are curling upward and cant find anything that quite fits, they feel slightly papery and thin, but the colors don't seem to be off...
heres a few pics, I'm growing with Canna coco, using the A+B nutrient solution with tap water (the pH was a bit low for my liking with M/O water) anyways, I've been watering just about every 2 days as the moisture in the soil permits, I'm running 400watts MH and the temp/humidity is at 80/50.

The plants are just over a week old now (started from 2" clones)

Any idea why they are cupping?

btw, they are on 18 on 6 off for lighting, light is about 7-8" from the plants

How often do you water?

I water about every 3rd day give or take depending on the moisture of the coco

I've done this like 3 times, so I know it's overfeeding. When the leaves grow all bunched up, and or only have 3 pedals to there leaves, it's a sure sign. Clones aren't as hardy as seedlings. You have to be easy with them. Next time try letting the roots grow a little longer out of your plug b4 you transplant them into promix with nothing in it for ferts. Feed when you see 5 or 6 new fully shaped leaves. With these ones I would flush flush flush. They Will come back, but it might take a wile. I wish I could blow myself.
