Hi everyone, I live in Northern California (zone 10a), and have just jumped into growing container citrus. I purchased two Oroblanco grapefruit semi dwarf trees which I am growing in containers. After receiving them in late April, I’ve had them outside and I have given them fertilizer twice with a 24-14-14 soluble fertilizer (instructions say every ten days, but I didn’t want to over fertilizer given I just transplanted them). I’ve noticed that the leaves have started to get a yellow mottle to them and I can’t figure out whether the issue is I’m over watering, under fertilizing, sun burn, or some other issues. I’d really appreciate any help. Mostly the largest leaves on top with most exposure to the sun, less so the leaves that are lower and more shaded. If there is some way to upload pics, happy to - Thank you!!

I think it's normal for new leaves, wait to green up. You have micro-elements deficiency, due to pH in soil since the semi dwarf rootstock is likely a PT hybrid. Maybe try a microelement spray.
