So these four seedlings where doing great then they just started turning yellow and looking like this. I added another light and that's about all that's different. Any help would be appreciated. Thanks.

They look over watered. Put some holes in the bottom of those cups and let them dry out. Only water when the cup feels "light". You don't need much light at this point. I've used a standard 100W led light bulb for four seedlings but put it close. I'm just a small med grower and usually do 4 - 6 plants.

are those delicate seedlings in the rain or what? stop the senseless misting
use t5, led, hid lights at least cfl. consider light feeding. more air flow, no dome.

I put holes in the bottom before I planted them. I was thinking over watering. I guess I'll water them even less. And I have an 100 watt CFL on them now.

Seedlings need very little water, theres no sense in saturating the whole medium when theres no roots around to use. I like to saturate my soil before i transplant not heavily enough to be wet, let that dry out almost completely then water around the rim with a bit to encourage outward growth and enough to penetrate a bit down into the cup. Then I will work on fully saturating my next few waterings as the root should be throughout. You can usually tell its time to re transplant when they start drinking what you water within a day, roots are nice and full. Yellowing could be from light being too weak or you could have them in a hot mix. Seedlings dont need any nutrients for week or so they have energy in their seeds, this is why you can start them in coco. Planting a seedling in any type of soil just risks it being burned. The plant produces those first 2 leaves (cotyledons) as a food supply for the plant if it needs it, so even it you start to get a deficiency you can watch those and just transplant. I always make sure i dont use a 100 percent of any soil mix Id go with like 25 percent soil and 25 pro mix and 50 perlite for nice aeration for early young plants in a 1 gallon from dixie. From that you transplant into a 50-75% mix of my soil depending on how well they do on the 25 percent. Its all about not giving the plant more than it needs and just enough. Less is more. Also dont foliar spray your seedlings, I believe you want to stimulate root growth by forcing them to drink from their roots. Foliar spraying when your medium is too wet will also show you signs of overwatering until it drys out the plant isnt able to transpire any of the excess moisture in the soil. All is not lost and sorry for the rant, you said you were beginner and I wanted to give you some tips/advice on what I do for success. Im sure you will get things on track its still a baby. Good luck man
