Help confirming seedling issues

Hey guys,

I have a few baby girls that I am trying to diagnose and come to a conclusion of some watering issue (under/over) and possibly pH fluctuations as I forgot to measure the ph in the reservoir (ebb & flow) for 2 days and it crept its way up to 6.5. I feed them once a day for about 10 minutes with only ph'd water.

They are about 8 days old (from seed) and reside in rockwool and clay balls.
They are under led light 24/0.

Note: All seedlings have slight/mediocre drooping

1. Slight drooping with brown spot on the right baby leaf
2. Slight drooping with yellowish/brown spot on right leave
3. Mediocre drooping with white line on right leaf,slight discoloration on left leaf tip
4. Slight drooping with white line on right leave center
5. Ends have yellowish white discoloration as well as slight discoloration towards beginning of leaves

The girls questions:


All help is greatly appreciated.

No.5 has some burning...overfeeding?

Never heard of over feeding on a water only diet. Suggest you feed them at a low dose and increase frequency of watering cycle if your hydroton is drying up between cycles.

After not feeding for a day and a half, I have confirmed that I have not been feeding them enough.
