Help! Seedlings curling bad

Is this a sign of overwatering? I noticed this happend in the past couple of hours after I watered my plants.. the soil seemed pretty dry so not sure what's going on.

Plants are about 1 week old, medium is Pro-mix mixed with perlite, worm castings, and dolomite lime. They're under 4 4' shop fluoro's. No nutes as of yet. Humidity at around 50%. Temp at about 75F.










Are they too far gone?

hello m8 i have same problem with hydro grow there 1 week old
hope some 1 can help as this is my first grow and dont want to lose them lol

Just checked on them this morning they still seem to be growing nicely but no idea why they're curling like this?

relax, don't over water, watch your heat

This is my first grow 5x white Russian + 4x unknown its a D/W/C hydro setup with 3x 15 ltr buckets 3 plants in each.

seeds were started on 20/08 everything was ok until yesterday when i noticed curling on 3 plants all in different buckets ive uped a pic of the worst 1
the nuts im using are canna veg A-B
PPM of tap water - 8
PH of tap water -7

i added nuts and bought ppm upto 14 for all buckets after halving tap water PPM so actual nuts added 10 PPM
added PH down to get 5.6 for all buckets

im using HPS 400watt on 18/6

they have been in buckets for 2 days
as there were no roots showing through clay balls i watered the 1in rockwool cubes before adding to pots and bought water level in buckets upto 10 mil below pots
sorry if this is a long 1 but wanted to add everything as it could help lol

Yeah I think they are just bending to the light a bit they look really healthy.

here are some more pics
cheers for the help m8

Still looking good . . .

nice 1 i was getting a bit worked up lol

everything is ok,
hey chill out though, because when they get more than 10 leaves, things get real crazy!

nice 1 m8 took me 7 weeks to get to this far just been getting everything together and doing alot of reading lol

um mine are like that too..... but it looks more like the leaves are growing upward instead of out to the sides.... but they are light greenish/yellowish in the middle like that too is that ok?

All looks good with nothing to worry about.

from wot i have read my nuts are a bit to high should be 400-600 ppm mine are at 1000 ppm dont no weather to alter or not
