As I stated earlier in this thread I used Heavy 16 for a few rounds. Actually, went through 2 gallon bottles each of the Bloom A and B. Ran Fire along with it as well until I decided I got better results coupling it with Big bud and later Overdrive. I was satisfied, but not overjoyed with it. Got good results for sure.
However, I recently gave AN's newish Sensi bloom A and B coco formula (im in coco) a run and results were noticeably better. My OG and Sour D look very similar (slightly better looking) to how they did with Heavy 16. The Girl Scout Cookies came out way better looking though. I mean WAY better. I scrapped the GSC thinking it was a fake and now wish I had not. It looks real deal after running it with Sensi. I still don't think what I ran was real deal GSC but it passes as some serious dank grown with Sensi. Couldn't say that running it with Heavy 16.
The Sensi is much cleaner and much more PH stable in the res. I ran it at 3/4 the recommended dose and couldn't be happier. Hey, I'm no AN superfan, but this stuff produced some jewelry quality nugs, and big ones at that.
