As for the PH I find that it really depends on how much Base A&B you are using. A&B will significantly lower your PH and most of the additives leave the PH alone except I found that Shooting Powder raises the PH slightly.
I have only done 1 run with H&G nutes but I have everything meticulously documented in a journal so I know that this is what happened in my situation, I cannot guarantee the same happens in yours but I will report back as I progress with my second grow using H&G nutes.
Good luck and keep it green.
As far as i'm concerned, H & G had pH perfect long before AN came out with their version. I used to test my Res every day or two to make sure it stayed in the right pH range, but now I just test once when I mix it and don't even think about it the rest of the week.
Hey guys when adding top booster should you drop your base nutrients a few ml per gallon just like shooting powder? Down around 800 ppm ?
I dont drop the PPMs when adding top booster. Only when adding shooting powder.
I use canna coco, haven't seen the hg coco in stores yet
I just finished a run using AT for the first time....I think it helps...maybe bigger stalks and more resin
