Your seedlings are fine. Feeding will make them green up nice for you. Just keep feeding light for now.
Prepare your big pots or bags for transplanting asap. You need to move them very soon.
Starting them in cups was a mistake.
Be sure that you buffer your coco before transplanting. As described. No shortcuts.
Set your light up high in the tent 30" above the plants about 65% power for veg.
Make sure you have EC pen, PPM pen and PH pen, PH up, PH down and Cal mag on hand. Mandatory for coco grow!
Your going to need a 5 gallon bucket to mix nutrients and a large runoff collector under your plants you can empty.
When growing in coco it is a type of hydroponics. You water at lest twice a day. 3 times is better. Runoff is 25% in order to flush the pot on an ongoing basis and not accumulate fertilizer salts in the medium. Get a pump up garden sprayer for feeding. Mix your solution PH test and put it in the spray bottle, spray around and around each pot until you have at least 25% of the volume of the pot in runoff collected. 3 times a day. Each pot.
