Yellow leaves

Hello.

I have problems with my young plants, I planted them outside on 20th june, I know that it was late.

Most of them have problem with lower leaves.

They are becoming yellow but "veins" of leaves are normal green. See attached photo.

What can it be?

My guess is, that it can be:

- too much water, it rains very often here, soil is always moist

- too much dolomite, I have put a handfull of dolomite with magnesium next to each plant, over the soil

Any ideas?

thanks in advance

This should help. Good luck.

They planted in the ground in native soil....or are they planted in pots with bag soil ....or in the ground back filled with good soil???

Looks like watering in some cal/mag would be a good start....but not knowing what there growing in to begin with ....we can only guess

Looks like Mag def IMO ....light leafs with green veins is usually a good indicator .....but the cause can't be pinned without more info

Thank you both for your replies.

They are planted in the ground in native soil. It is very fertile.

Looks like a mag def to me as well. I would definitely start adding some calmag as a starting point.
