Wow sorry to see the devastation Blazin those plants took a real beating. Luckily I caught the PM in time on my crop it was going from ugly to worse but I was able to neem oil them in time to save everything. At this point along the game for you the best bet is to cut the affected fan leaves down to keep the buds from rotting. I wouldnt recomend foliar spray your pretty far along now and if you foliar fight the PM your buds will rott from the residual moisture. You can try feeding it a neem oil solution and possible some nutrient high in silicates to help keep the plant defenses up, flush well at harvest though after usage of neem! Good luck interested to see how it turns out dont smoke it if the buds are contaminated you can get very sick from that.
