HELP Baby Seedlings Leaves turning Yellow

Hello all, I am working on my first grow and have just started the seedlings on nutes. I made a windowfarms and popped my baby seedlings in them and all are fine but my biggest seedling. I am running a 200 ppm advanced nutrients perfect ph micro with a drop of strive in 2 liters distilled water. PH is at 5.8 but hovers up to 6.4 brought it back down with a couple drops of vinegar. I only flow water through the system once every day or so. Also, I am using 500w of broad spectrum led lights.. Any idea what I am doing wrong? All help is appreciated. Thanks in advance

I'm gonna say it's not rooting because there's something about your hydroton it doesn't like.

thanks, I was worried I might have plugged them in too soon, should have let the roots reach out a bit more I guess, any solutions?

Anyone? I am really worried about my babies

Please save my seedlings!

Something went wrong with the app of nutes, calculations whatever its burnt and as good as dead bro, be more carefull ,is that coco?

Even though the yellowing occurred before the notes were added? Any idea how to avoid this in the future? Thanks!

Did you feed your plants r/o water or tap water prior to adding your nutes and was it ph'ed? Also you don't need to feed your plants any nutes til the second set of leaves. It looks like you have your seedling in a rapid rooter. Did the roots root out of the rr before putting it in the window farms?

No I plugged it Ito the widow farms when I saw the second set of leaves, the roots did not develop at all the seedling died and molded and when I checked the Ed there was a single thin strand of root inside, the other plugs have white healthy roots poking out all over the rr, I guess next time I should let it germinate longer before plugging it into the system? The water is distiller by the way, next time what should I use for the the seedling and when should I start nutes? Thanks!!

I start my seeds from rapid rooters and use a stinkbud style aero cloner. I use ph'ed r/o water that is at 0-10 ppm. Once the seedlings develop a second set of leaves and have rooted I give them nutes of about 200 ppm.
