Seedlings Turning Yellow

Hi guys,

Sorry another beginner in need of guidance. I have some seedlings that are turning yellow... The yellow tint seems to be coming from the centre of the leaves rather than around the outside. I havent given any nutrients yet other than the fish blood in the soil.

Can anyone help me please as I'm a bit lost.

Thanks in advance

What are you watering with. Look like iron....

But its weird to it on a plant that young. Thing that can cause this are overwatering, not good enough drainage in the pot, high PH, over load of p, or excess zinc, manganese, or copper... But again I've never seen this in a plant so germinal. What lights are you using and how close are they placed?

probably overwatering.

Thanks for the quick response guys, I'm watering with tap water and the lights are LED's so very little heat. I was thinking that I may have over watered them.... not sure I put enough perlite in the soil.... Should I re plant them? The PH is fine I check it every day. Thanks guys.

Ok went ahead and re planted them anyway lol.... guess I'll see what happens
