Leaf readers - can you tell me what's going on?

These appear to be from one type of seeds I got from someone. I'm hoping its not a seed transmitted disease... so I don't have to throw them all away and be worried that's its now in my grow space :/
I should clarify, these were growing indoors and have not been set out! I was using a weak solution of MG.

I'd lean towards nutrient issues but not sure what.
Is it possible the soil got a heavier or lighter feed around that one plant?

Pure, I should clarify, these were growing indoors and have not been set out! I rather its just a nutrition deficiency. I was using a weak solution of MG. What you're suggesting DID happen so this is great news!

It looks like nute burn to me, which would be too much fertilizer. It's easy to do with Miracle Grow, especially if all the blue stuff didn't dissolve fully in the water.

I've intentionally tried to burn up seedlings with ferts, it takes a lot generally. At 50℅ above recommended some seedlings didn't even get burned tips, some did, but general health did not demonstrably suffer.

My guess would be nitrogen deficiency which could be caused by lockout in the media from to much fert or keeping the soil to wet + the fert. I have been experimenting with lots of things this year and after too much fert my plants looked like that and continued to get more yellow until I treated them with Calcium Nitrate. I also tried MG, epsom salts, and fish emulsions with kelp alone and in multiple combinations. The Ca(NO3)2 worked best, as in all plants are 100% recovered, so my assumption is that from over fertilizing the plant I locked out the nitrogen and the plants couldn't get it until I provided a more readily available form. I'm no expert though, and it seems trial and error is the best way to learn.

BVV, I've been doing 1/4 tsp per gallon but perhaps those got a clump of undissolves granule. How much CaNi do you think to treat?

I used 1 tsp per gallon. and used it on 1 tray of seedlings.
