This stuff is great!
The pH on my cannabis plants was at about 7 1/2 almost 8. They were not taking up nutrients like they should, which is obvious by their stunted growth and within one water and using pH down it… Problem solved! Perfect, 6.7 PH. All I did was mix my feeding solution take the pH, Then add pH down until the pH was at around 3 1/2 which I figured is half of the approximate 6 1/2 I was looking to get. And it got me there right on the line. The only problem with this product is there are no real directions. You kind of have to do trial by error and let me tell you folks please err on the side of caution. This is straight acid that will definitely burn your plants so do not apply this directly. Do not apply this in high doses. I would say start with a cap full in a gallon of your feeding solution and then go from there, adding more until you get to where you want to be. That said, I kind of understand why the directions are the way they are because every solution is a different pH, so there is no perfect amount. It’s always going to be based on your water quality and the pH of your nutrient base. At any rate, I will tell you that this product works absolutely great. I would avoid getting it on the plant itself and apply only to the soil. Happy growing.✌️🙏❤️🤩🌱🌳
