any ideas as to what this is? it's started on the super sweet 100's and i see a bit of it on the sun golds, seems to be on the fairly new growth as opposed to the older leaves.----thanks tom

guess i'll just spray the heck out of it with copper spray and hope all the green ones ripen up fast,

It doesn't look like a disease to me. Purple leaves can be caused by cold nights, and also by a phosphorous deficiency.

after they get like this , then the edges turn brown and crispy, mostly on the new leaves that are emerging.

Isolated to new growth? Seems like it could be fertilizer burn or drought stress. I can't see the last image very well, but it looks like it's always dying back from leaf tip and not from the base. New growth dying combined with the pattern of tip to base browning seem to point to a nutrient or moisture issue
