View attachment 867119 ...those bugs are juvie Springtails, no menace there, just annoying,... they eat decaying matter, fungal hyphae, that sort of stuff, not live plant/roots that I know of,.. they are ubiquitous and exist in
staggering numbers, no getting away from them outside! Easy to kill if needed, but brushing off the pot will do just as well,...
I am relying on my eye sight for this one, but I am quite convinced that those are the critters. Well if they don’t harm, they may stay, and it is outdoors after all
I’ll try get a magnifying glass! Sorry to hear about the bug wars, it can be devastating!
As for the plant symptoms, they don't match up well with any defc/toxicity,... it looks kinda like an infection, fungal,.... the "wet" pre-necrotic margins on this leaf in front of the dried dead tissue is the hint I'm seeing,... that and the wasting pattern,... Just to be thorough, what P sourcing/nutes are you using?
