Hmmmmm .... that makes sense. Hopefully, others will chime in here to verify or disqualify our theories and/or photos about leaf streak and typical leaf dying.
I have both leaf discolorations in my garden beds, just like your photos. I will take some photos tomorrow of what else I am seeing on my leaves. Pests are another whole ballgame!!! Do thrips affect the leaves? Or just the blooms?
Explore one idea, only to branch out into another idea and .... topic! Does it ever end???! LOL!
