yellow edge?

hello everybody.

I just started an nft project with lettuces in them.

the plants are nearly 3 weeks old. I notice a yellow edge on the leaves.

I suspected magnesium deficiency so I foliar fed them with calmag solution yesterday. am still not sure if it will do its thing. am running 20.20.20 fertilizer at ec2.2 ph 6.3

the photo is of today.

any advice is very much apreciated.

thanks a lot
