Did I mess up?

Hey all, I've been working on my room for a few months, I figured I'd do a few GH Sweet Mango autos outside since we're just coming into spring where I am. I germinated 5 seeds in paper towel, then put them in jiffy pots with a peat based seed starting soil. All five made it out of the dirt but two of them didn't fully open to show the first little round leaves. The three left have been doing well in the jiffy pots by putting them near a sunny window during the day then under a flouresant light at night with several hours of darkness.
I started the seeds with distilled water with a 5-10% hydrogen peroxide. Just after the second set of junior leaves opened I started with a tiny bit of food for them. I'm using General organics "root booster" and "bio thrive grow" at a very minimal concentration of approximately a 1/4 (0.3ml in 500ml h20) of strength that would be used after first true leaves appear. I've only done 2 feedings with this but with several water only feeds between. The seedlings appeared to be doing fine like this, I however thought it'd be nicer for them under better light so I got a sun blaster 200w 64k bulb that I've rigged into one my my silver star shades usually used for my hid lighting and moved the seedlings under that.
I was also noticing one of the seedlings was yellowing a bit so I decided it was time to move them up to a 3gal pot to grow and veg before I move them to 5gal.

The reason for my post today is that the leaves are curling under on all the seedlings, I don't think I've used enough nutes to nitro burn so I think it's most likely that it's either shock from the transplant or they've gotten too much water from being in the big pot.
The last thing I should mention is that when I transplanted I didn't just put the jiffy pot in the new bigger pot, for whatever reason I was worried even with soaking the jiffy pot in warm water before the transplant that the roots wouldn't like growing through the pot, so in the process of getting the seedlings out I may have left behind a hairlike roots in the bottom of the pot.

I'll attach pics of the seedlings and also the light set up I'm trying for seedlings and maybe mom in the future when I get on my Mac as this forum won't allow me to do it directly from my phone. Hopefully someone can tell me if this is normal, water related or transplant related? And if it's water what's the best way to save them? Replant in dry soil? Put a space heater next to them to dry it out?

Post some pics pls.

Let's see her.

sounds like you're messing around with them too much

Pics are up. Top pic is the plant that was yellowing for no reason and what made me decide to give them a bigger home then the jiffy pot. Second pic are the new curls, and 3rd pic is the little light set up I'm trying with the 200w sun blaster rigged into my HID shade. Barn Buster I'd agree with you I have been trying to baby these plants more then any other just because of the cost of seeds...think I've learned my lesson...

Hold off on the nutes soil should be providing all it needs right now.

firstly you dont need to germ in paper towels. secondly you need no nutes for the first month with good soil.

good luck and hapy growing

Thanks for the advice guys. Haven't been growing long, usually I'll just germinate in soil or the little jiffy cubes. However the seed company recommends pre soak then the paper towel method for their seeds so I had to give that a go. As for the nutes, I'm trying a new kind and the store person seemed legit when they told me that even a weak solution for seedlings was a good plan. She stated that the nute company's just want to sell the stuff so the overal strength they recommend isn't necessary and that I could get away with only half the recommended strength for my adult plants. So when she said that I can feed seedlings a weak solution too I believed she knew what she was talking about and wasn't just trying to sell me more food.
