Yeah, I would just not panic and do anything that will hurt the plants more than the bugs. The neem oil works wonders for my outdoor garden but in bad soil cases I have to apply it heavily every few days and get the plants vigorous. I really love your low wattage setup, it's seriously inspiring. I bet that is going to be the best little stash you have ever smoked...especially since you earned it!
The problem is, since it's slower growing the plant won't stay ahead of the infestation with out a lot of assistance. Next time start super clean and look at keeping bugs out better by air filters or something.

I would guess it still has three weeks but it's hard to tell from here.

Keep it up!
