Yellowish-orange patches on leaves

I've got yellowish-orange patches starting to show on some of the leaves of my young dwarf citrus tree. They're developing in between the veins of the leaves. If I could find my camera, I'd send a photo.

Any suggestions?

Look for evidence of scale on the underside of the leaves (If they're pactchy yellow discolaration), you'll find white & black speckles of scale infestation. Need to spray you shrub throroughly with appropriate agents (for fruits crop). But, if indeed it's just yellowing and discorlation of the leave's veins. It maybe a sign of iron deficency. Fertilize your shrub with a balance fertilizer one with added iron.
