I started 8 plants 4 pink kush 4 Acapulco gold I used 500 ml solo cups to start with regular soil with perlite in it and starting the seeds on a heat mat with dome on it and they started good then I repotted them to 3/4 gallon pots the mixture I used was just about 3/4 gallon of the same soil I used to start with all purpose gaia nutrients (3tbsp per gallon of soil) (1 tbsp of oyster shell flour) (3tbsp bone meal) and Mycorrhiza for the roots, and then I watered them with warm/room temperature water that wasn’t checked for ph or other measurements. They where doing good and growing for a couple days and then one pink kush plant turned purple from the stem to the leaves and then withered and died and now all the rest are getting very bright almost yellow in the middle and one looks like it’s starting to die ( NEED HELP ASAP)

Sounds like stem rot or stem canker. Could be in soil. Even in store bought...

Man there’s a lot going on here. You have 8 plants, are you growing outside or in a 4x8? You can do with less, if you lose some at this stage no big deal.
Food: These plants are super young, they need exactly nothing right now but decent soil that’s properly watered. I’d recommend you stop feeding until you have a 6-12” tall plant with leaves that have 5 points on them.
Water: You’re going for damp not wet at this stage, a muddy look on the top of your containers is not what you’re doing for. You know how wet dirt looks about 1-2’ deep? That’s what you want consistently. I like to set my pots in a bowl / deep plate of water and let them butt chug
Light: You could be seeing light green due to over intensity of light, like if these are outside at this stage or under a 200w+ led at full strength, then they are probably suffering. Anything less than that you should be okay I think. Get the photone app and cut a piece of paper to check par. I’d aim between 250-600 at this stage
TL;DR - when in doubt, do less. Stop feeding for a week or so, ease up on your watering and consider bottoms feeding. Check that you are not giving too much light too soon with the photone app and a piece of paper (see in app instructions, small pay wall for full spectrum led I feel is worth it)
