Also I want to add a little side note on the Sensi pH Perfect Coco Grow I am currently using, along with the Voodoo Juice root stimulator. As the pictures show, my plants seem to be doing great. The thing is I am doing something that most people using this product would say I shouldn't do. I am adjusting the pH to exactly 6.0-5.8 with pH down (General Hydroponics). I have a pH pen and I felt uncomfortable knowing the ph was only adjusting to about what the recommended pH for soil would be. At 1/2 strength nute's, I'm adding 3 ml of pH down, and for the 2 week old's + plants I am feeding 3/4 strength and I add 2.5 ml of pH down to get to the sweet spot (using 1 gallon containers). So far as you can see the plants seem to be liking it. Also as I stated in one of my updates, run off tested at 6.2 pH. Maybe this would be a non issue if I were using reverse osmosis water, or tap that was at 7.0 ph. If your tap is 7.0-7.2 you more then likely would be right on or below 6.2 pH without needing to adjust with pH down like I am.
I just wanted to add that for anyone using tap at around 7.7 pH and using the Advanced Nutrients pH Perfect Coco line, and felt the way I did and wondered how adjusting the pH with another product would react. So far so good.
