Could use some help! New to hydro

I am growing for the first time and my seedlings are about 6 days old now and about an inch tall, but leaves on two of them are curling down. I imagine this is a problem, could someone please tell me how to fix this?

Thanks

do not feed Nutes.

is it the round leaves curling down or the pointed pair?

Need more info, what hydro, nutes, ppm's. ph, lights? sounds a little like not enough light but without info hard to say.

There are no nutes, the ph is 5.6 the ppm is is about 550, i just used tap water but i found i should use distilled water. the lights are 3: 6500k CFL Grow Bulbs

550 ppm out of the tap? Bajeebus. 3rd pic looks like a normal plant, but it could be the angle not showing the downward curl. I've only got that from over saturation, but your gnarly tap water may have something to do with it.

How to i not over saturate? less water?

and i will get distilled water asap to see if that helps

The ppm is about 260, i made a mistake earlier and was looking at the ec meter.

How close do you keep your lights, i still feel it's lack of light, tap water is fine, but I don't think it has all the nutrients needed by your plant, distilled would be to my opinion worse, there's less minerals in it, personally I'd give it a small amt of nutes, if water 260 I'd add 40 ppm's nutes, 'course that's just me.

Edit: Somehow I get the feeling you may ask " how do I add 40ppm's ? ", just mix a small amt of nutes ( say 1/4 or best 1/8 strength ) and keep diluting with water 'till you reach 300 to 350 ppm's.

Less light, less nutes.. more light, more nutes.

Distilled water will suck the nutes from the seedling.

Thank you for your comments i got more lights added nutes and i won't use distilled water
