I need an Expert or Magician - this time with pics

I am at a total loss. Let me explain.

Been growing for several years,
using ebb & flow
Bagseed growing in rockwool

Well water that is about 75 PPM
GH nutes taking water to about 250PPM
PH around 6-6.5
Fouros for 18 hours a day
1 watering (30 minutes) every day

OK, seeds sprout and start to grow until they get about 1-2 inches high. Then the lower leaves start to turn brown and the plants slow down their growth. I can't figure out what has changed. I hope you can give me some hints.

Are you adding in the nutes (after) the plants have a few sets of leaves? Or are you adding them to your system as seedlings?

I am adding nutes to the seedlings. They didn't really need them but I am trying to find source of problem.

If it where me I would wait to add in the nutes until they are a tad bigger and not in seedling stages of life. I usually start feeding any of mine when they have around 3 to 4 sets of true leaves started. If feeding is done before that they just cant handle it. Looks like what may be going on here imo.

thats the problem then bro.. You have to look at them like they are babies. the food is just to hot for them in their younger stages of life. If/when you do start some new ones, just place the seeds into your medium whatever you decide to use, use plain h2o that has been ph'd to 5.5 is what I had tried to keep mine around when I had ran DWC. At that level they seem to accept the food better.

I thought ph should be around 5.8 for seedlings. I only got 1 DWC bucket going now since im a soil guy but i keep my ph under 6. When it has hit 6.5 it shows on the leaves that it doesnt like that high of ph.

I was stating the ph I had kept mine at when running the DWC. Its a wide range though from 5.5 - 7.0

You wouldnt feed a seedling though is what I was trying to get across to the OP. They usually can make it to at least their 2nd to third node/leaf sets without any nutes. Then I would just start off with a lower ppm with my nutrients & work my way up to where I wanted my nute levels. If they ever showed any signs of over feeding I would just back off a tad.
