Why aren’t they more green?

your temps are a bit high, try to get that lower if you can, have you been checking the temp in the buckets?? keep those roots nice and cool, and make sure you have an air gap under the pots, last tip check your ph everyday in your buckets, it will drift on you over night. other wise you will be really happy cause the grow looks great. when you grow dwc it is real nice, and you will have a huge harvest when its time, happy growing

Hey man, just checked your video! It’s hard to say without knowing your EC, PH, etc. But since you’re going with hydro chances are they need more nutrients! Hydro even with seedlings still need light nutrients because you are growing in a zero nutrient solution (water) I’d start with a vegetative nutrient at about 1/4 strength to start and see how they respond. But usually light green leaves always means they need more Nitrogen! I’d also keep your ph in between 5.6-6.1!
