Leaf edges curled up literally on the end. And light green. Just transferred to dwc roots are hanging through the net pot and getting bubbles on them (splashing up). I have 19 w feit grow lights (3 of them) and a full spectrum Chinese light from amazon 60 w (probably 20 lol). I think it may be light stress (it was 10 inches away) I just raised them higher to see.
Water temp is 72
Rh low ( I dont no exactly need a meter)
Ph is 6.15
Ppm is 400
Advanced nutrients lineup for dwc
Not sure water else I can provide.
I added a bit of cal mag an hour agi just to help.

Thanks for the help in advance!

OK just did that earlier, the leaves are reacting and still lifting up since I've raised the light, I had it close because I didnt want them to stretch, plus there weren't in a tent. which always cause the temps to rise alot. probably a combo of both I'm guessing. Thanks so much!

Seedlings can sometimes throw out wonky growth as it gets started. I'd just continue the feed schedule you're using. You will need to top feed until you get enough root mass down into the solution.
I'd also plan on filling the netlid some more. Light leaks will generate algae gowth.

i dont grow from seed often. i run clones.. if it was me i would not of put that seed in to a dwc bucket yet. i like my rockwool blocks to be exploding with roots before placing it in to the net pot. then i will top for a few days. once a decent ammonts of roots hit the water. watch your plance start growing fast . untill a decent amont of the roots are in the water. you will see some deficiency. i think because the plant wants to grow faster then the nutrients it can uptake. being so little roots in the water. give it a week ill be happy again. just keep ppm ph and water temps in check until then. id start looking at more light with in a few weeks

Know your RH because if you dont know it and its low, its going to cause all kinds of shit like that and you will chase phantom problems all day.
Your lights are 100% something you just have to figure out trial and error. Raise them to about 2 feet and measure what the seedling does. If it stretches lower them down a few inches at a time. Once they don't stretch much you are in the right zone. Seedlings like that do not need much light at all.
Yah, and let that rockwool dry out. Once the roots hit the water it should dry up and stay that way.

Will do for sure just was waiting for the stem to go up tiny bit more. Roots are about 4 inches into the net pot! But thank you really appreciate it!

Definitely ordering new lights, and thanks for the info, my question to you is if I leave the rockwool to explode more roots which I agree is better, what should I do when the roots all grow out past the Rockwell, wont the light affect the roots? Ty again

Ok great thanks for the tips! I noticed that there are very very small rust spots like 2 or 3 but barely noticable,I'm assuming it's because it's so small? So maybe magnrdiun issue?

LOL magnrdiun.
Nah man, it doesnt have any deficiencies. If your ph and ppms are right just trust your system and try not to read too much into stuff for now. Let them do the thing and get big. Manage your basics and your plants will respond accordingly.
I repeat. The worst thing you can do is stare at them and imagine every spot as something. Just be glad your in the ballpark for now.

Question??? Hi I'm growing down under...ordered 15 reg seeds, hash bomb, Old Skool, have 4 seedlings in coco coir one week old using Hy-Gen nutes from Tasmania. 15ml of A+B+10ml of Budlink-Silica under 400watt HPS and a dual spectrum 125watt CFL. I also have a six hole DWC shoebox shaped with Net cup's and sponges+air stone and pump 4 gallon resoveir with tiny sponges it doesn't look like it could produce or withstand a good plant but am curious and will try cloning in the DWC system if I can. I still have another 5 I hope will be successful but just being patient atm and letting them do their thing. Any help welcomed
