I am trying ph perfect MGB in soil and was wondering if they work regarding keeping ph in sweet spot ? Any advice would be appreciated. I

@Mr. Grow It yeah that's the one ..

@bryanrenicks64 I haven't tried that lineup so I can't tell you for sure if it works or not, although, once you mix the nutrients according to the feed chart, the pH of the nutrient solution should be in the ideal range. Keep in mind that there are many things within the soil that will adjust the pH so you'll still want to monitor the pH throughout the grow.

@bryanrenicks64 I use an R/O water system along with M,G,B, as my base nutrients. I add Cal Mag to my water as well. But to get to the point my ph comes out at 5.8 or 5.9 every single time. Run off in the soil almost always comes out between 6.1 and 6.4... Hope this helps.
