I wouldn't say I've gone to the full AN line up. But I suppose it is mostly AN.
I run AN Sensi bloom (coco version) A and B along with AN
Big bud (coco version), AN Carboload, and AN Overdrive (regular version) the last 2 weeks before flush. Also run
Hygrozyme nearly every watering. Occasionally I'll dose them with an ml/gal of
Sea Green. Also run
Botanicare Cal Mag Plus through week 5 or 6 (I use 75% R/O water to 25% tap, tap is 250 ppm) and Protect silicate.
As far as my observations between
Heavy 16 and AN, I've found that overall bud leaf seems to be less with AN compared to Heavy. The finished nugs are prettier with AN since there is less leaf. Also I find that there seems to be larger trichs, and more of them with AN. Yield seems to be about the same with both.
As far as Fire compared to
Big Bud, I found that
Big bud was much better as far as early bud growth and overall nug size at the end. I felt like Fire was a big waste of money. Saw a drop in yield with it compared to
Big Bud when run with
Heavy 16.
