Recently all my in-ground in-greenhouse citrus had large growth flushes. The new growth is looking very yellow/white now. It seems to match up with spider mites, the trees that haven't had much spider mite activity are still nice and green, but the ones with the most spider mites are most affected. Are spider mites the likely cause, here? Or is this more likely a nutrient deficiency?
I just did a ph test and soil is ~6-7ph. I added a handful of osmocote to each tree a few weeks ago. Soil doesn't seem wet, at least in the top inch or two I could dig my finger into.
All my container-grown trees outside are unaffected.
Here's the Flame grapefruit (I think):
And the Moro has some really bad areas like this:
Even the Valentine Pummelo that Millet sent me is affected, and it is on flying dragon. The rest either I don't know the rootstocks, or they are some non-optimal ones like C35
