I hear you on the exorbitant prices of H&G nutes but this is one of those cases of "you get what you pay for."
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.
In regards to pH, are you on a well? I use RO and since I moved to a place with a well, my RO is 3.7 or so and the same when I mix in A & B. what I foun is that it's dissolved CO2 gas from the limestone. If you circulate your RO tank is will gas off. If not you will add up to get it right then it will gas off and you will have to add pH down
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
