Yellow dead Looking cotyledons

[Hdk40]

Hi all, germinated 3 cereal milk seeds 2 days ago, I’ve got really dead looking yellow cotyledons on all…mistake I’ve made is putting into nitrogen rich soil. I haven’t had this issue on the previous grows but I guess this strain hasn’t taken to it and I’ve been abit lucky on the last grows. They seem to be still growing but you think I should start over here? I don’t really want to carry on if these will be stunted or even get that far…

TIA

Keep domes on them for 100% RH and give them a gentle flush with plain water....lots of it. You'll wash away the nitrates that are causing you problems.

It may not be an excess of N causing the yellow cotyledons. Thiscan happen in nute free coco also when they break the surface. They will green up quickly nirmally.

Thanks Bluey they have the only just come through now. They are in solo cups with domes and air holes will check on them tmora

Keep them moist. You can foliar spray some nutes on them at EC 0.2 or less without issue.
