London pound cake

What application rates are you using? There's a weak solution, a medium solution and a strong solution... I presume (and hope) you're using the strong solution? The 2.5oz to 30oz of water? And you're spraying the tops and bottoms of all leaves as well as the branches and stem, buds? I've got to say, looking at your diary, you've got quite a jungle in there... and I think it might be easy to miss spraying some stuff. If this was my grow, I would take each plant out of the tent, spray it, leaving them out of the tent until every plant has been individually sprayed thoroughly and then clean/spray your tent before putting the pots back in there. It really DOES work but having to deal with an infestation when you're plants are as large and leafy as they are is challenging... and I don't envy you at all. The only other thing you could do would be to try some Spinosad - but you're going to have to go through that same procedure... Good luck! Nasty little bastards they are!!
