^^ These two sprouted first

And another like this(this one seems fine):



About 8 days into growing. Please Help!

im doin the same grow atm... around the same stage aswell. 1 of mine had brown tips and a couple of holes but the newer leaves are lookin fine.

Sorry for bumping a old thread,

but i have the same problem and cant get a pic right now,

can anyone diagnose it please?

thanks.

Does anyone know what this is, the first pic?

its on my week old seedlings, and is spreading to all leaves, and slowly making it from the tip down

Does anyone have any idea what this is?

maybe nute burn?

Nute burn? Do you mean from the soil? I hope you are not giving seedlings nutes already. Just let em grow, no ffing nutes in the seedling stage, all they need is light and don't let the soil get too dry. Simple really. Make sure you have a few pinholes for drainage in your plastic solo cups, airflow to roots is important as well. Just leave the nutes out of the story until they are at least a month old.
