What is going on with the lower leaves of my lettuce & lavender, and all over my basil? See the pics. Some kind of infestation? The tomato and pepper plants in my Click & Grow 9 do not appear to have the same leaf problem.
I’m so sorry, but your plants are infested with thrips. Those white areas and black spots show that the damage is already done by thrips. As you zoom in you see pale long bodies that are thrip nymphs that are ready to infest other plants.
I would recommend throwing those plants away asap and clean the garden and surfaces around it carefully.
You will find more tips on how to fight thrips in this forum, just use the keywords for search.
