My seedlings are 2 weeks old.
I did stunt them with to much light and overwatering :(
Anyone know what this discoloration is on my cotyledons?
They are in PRO-MIX HP (peatmoss and perlite) watered with 6.5PH tapwater.
From what I read it looks like it could be the start of a manganese deficiency?
Its only happening to my Blueberry cookie seedlings. All others are unaffected.
They will naturally die off and the discoloration is not a sign of a deficiency. The cotyledons only supply the plant with nutrients for a few weeks during early development. Your plants look fine.

Hmmm, I was told that they are good for 2 weeks. Just looked up their MSDS and it indeed says its "essential" to fertilize after first 7 days! Thankyou for saying this cause I was not going to feed for another couple days. You just saved my babies even more stress!
