plants have stopped maturing

So I have harvested about half of my crop, but now some strains have entirely stopped maturing. I am at week 10 of flowering right now, and the rest of the crop's pistils have stopped turning red, trichome production looks to have stopped, and trichomes all appear clear to cloudy throughout. This is most pronounced on some Extrema that I have going, which is supposed to mature after 8-9 weeks of flowering, yet yesterday was 10 weeks since switching the lights. Has anyone encountered this before?

For the record, the extrema did veg to 1.5 feet, but I don't think that should affect flowering time at all. Also, I used Ed Rosenthal's solution to combat some spider mites I had a while ago, which burned many leaves, but once again I don't think this should affect flowering time.

Thanks for any and all advice, I could certainly use it!

Are you using a bloom booster? It could cause your buds to take longer to mature(if not at least I bumped it for you).

I'm using herculean harvest by nectar for the gods, but it's just a calcium/phosphorus supplement. Thanks for the bump tho. It's sad though, I don't know if I should just harvest early or wait to see if things progress.
