This is a summer squash seedling that I started outside due to the unseasonably warm spring we are having. Yes, I know it was risky, but I took a chance.

I planted 2 of these seeds, and I got 2 seedlings. However, one of them was yellow around the edges the first time I saw it, and then the edges turned brown and dry.

I have another seedling coming up in the next bed that is coming up completely yellow.

What went wrong? Water? Lack of nutrients? Frost damage?

These are both planted in self-watering beds and my water sensor says that they don't need more water. Mind you, the bed could be over watering, and I wouldn't know what that looks like.

Pictures can be found here: Squash Seedling - what went wrong?

Thanks for any ideas!

The last photo does look like over-watering to me. The yellow edged ones I wouldn't worry about until the first true leaves emerge. The cotyledons(seed leaves)provide the first nutrients to the plant(which is why you don't fertilize new seedlings)and will yellow, wither, dry up, etc., as they are used up by the plant. And, they can be damaged trying to emerge from the seed coat, as in your other post. If the true leaves show signs of yellowing or rotting, then you should be concerned.
