Need help, first DWC

[Midwest Grower]

First dwc grow, would appreciate any help.

Lights:
Osram Zelion 3x2 160w - 2 feet away from medium.

Nutes:
Botanicare Pure Blend Pro Grow

Equipment:
2-5gallon buckets
2-6 inch net pots
2-tetra 10 gallon air pumps

So here’s the issue, started bag seeds in Rockwool. Once the tap root broke the bottom of the wool a inch, moved them into the net pots. Sat them on top a layer of clay pebbles, set water to barely bubbling to the pebbles and sat the cubes down and covered with pebbles. They sat there for 4 days and no roots. I lowered water and finally some roots. Now a little over a week in I still only have coly leaves and 1 set of leaves, the second sets are barely coming in and now one of the babies is starting to turn yellow and wilt. Bottle of nutes said 15ML/Gallon of water. I added way less, 7.5ML total. I’ll try and add some pictures here soon. PH and PPM meters are on the way in the mail, With liquid PH tester I’m around 6-6.5 PH. Probably next week I’ll move to RO water and add calmag to the mix. I added nutes AFTER the wilting to see if that helps, it’s been 24 hours and it doesn’t seem to be getting worse. Any help is appreciated.

I would mist them daily with a 10% solution of adult mix nutes. So you mix the nutes at 10% of the listed rate. Once they start to bolt, increase the solution nutes and stop misting. My RO water here needs 2 ml of vinegar added to 5 gallons to get the ph to 6. With nutes its the opposite, 3-4 ml of PH down to 5 gallons of water so I always check the PH last.
