Thats what I figured about P Thai. Can't remember the exact date but around oct 7? So I would go for that blueberry you talked about. Serenade is the best hands down but I use it from in veg before the transition to about 2 1/2 weeks before done. The smell is so bad but it goes away and has never effected smell taste or anything of mine. People who get mold then spray it thinking it will stop dead in it's tracks are the ones that the smell stays...cause it is fresh serenade plus mold! It is made from rotted peach pits I believe...yuck but it does work and my way of using it seems to be good. Good luck man.
