Thanks. I've been trying different things for a while now. I used to check my ph but stopped about a year ago or so when my pen died. Maybe the rain is a little more acidic because of the volcanic activity or something. I used to mix nutes with the county water and use the rain water on the plain water days. The Pahoa county water has been a little smelly, so I stopped using it a few months ago. I'll get a new pen and start checking it again. I have the issue on one of the A/N plants as well as a couple of my Jack's nute plants.
I don't usually foliar spray, but I did a last spray for bugs when they started flowering. I also have open sides where my plants are, so my plants do get wet if it's windy and rainy. I've been noticing flies on the plants quite a bit. I was wondering if they were somehow biting the leaves making the spots.
As for the leaf miners, I don't usually try to do anything.
Thanks for looking.
