Looks like a zinc deficiency to me along with iron.
Now on to what nutrients if any you maybe using?
Also what’s the white flakey matter all over the plants?
Epsom salts?
If so pls get some proper cal mag, it has the macro nutrients that your plants need.
Vitamin b1 helps when transplanting for root development.
Also looking at your soil, it’s very wet.
Transplant shock.
It’s common for folks to start aggressive watering post transplant, avoided this. Only water when the 2-3” below soil top looks dry. Or do a weight test, 50% from wet to dry , you sprinkle water at outer perimeter.
Remember we are encouraging the plant to put out roots, this only happens if we try to starve it a bit to allow the plant to send roots out.
Hope this helps along with a few charts I attached.
Also it can be rust fungus, if it’s in a humid environment, if so actinovate works wonders. Most hardware places carry this. It’s used in lawns for fungal control.
