Very slow single leaflet deterioration

resimaxstarted grow question 4y ago

Can anyone identify the cause of this issue? Note that this is occurring on only a single LEAFLET of a single leaf of a single plant. No signs of eggs and it is very slowly spreading. Took 5 weeks to get this far and starting to spread to leaflet next to it with some small spots.

Well, it's got to be an insect of some kind as a nutrient issue or environmental issue wouldn't cause this kind of damage. I'd get some BT and spray that particular area - top and bottom of leaves - just before lights out. If it IS a leaf-chewing bug, it will take one bite, decide to have lunch elsewhere and go off and die... and BT is organic so no worries there... Good luck - that's just weird!! :-D

I have brown spots on some leaves lower down on plant. Have looked it up on internet and think it calcium deficiency. But I use Cal Mag. Could it be something else? I have picture up on diary.
