greeneyes:" He just brought in some to show me, and they have some sort of discoloration kinda taupe colored on the stem end."

Sometimes 'sunscald' will stain on both fruits and stems , although it may be more tan colored than taupe
the only correction/ assist might be shade cloth.

Weird that it is only on the roma’s. All the buckets are grouped together in the same space and filled with the same potting mix.

So far no problem with the others. Are roma’s more sensitive to sun?
