This is my first run with remo nutes. Prior to this I was a general hydro user. I didn't have bad results with gen hydro. I was convinced to try remo on the premise it is a marijuana specific feeding schedule. I have been very happy so far. My observations have been faster growth/development and generally happier plants. Now I must admit sometimes that can happen any time you change something because you tend to be much more deliberate with your techniques being careful you don't screw anything up with the new formula. I also changed my lighting setup a bit which has definitely shown results in much denser buds and trichome development. As for the nutrients....they mix pretty well. The micro and astroflower both need to be shaken before measuring out as those two tend to seperate out in their bottles. The grow, bloom, and manifical are all very consistent. I don't use the kelp formula. I still use gen hydros hydroguard and floralicious plus. I mix 20 gallon batches at a time and they hold ph very well. As far as root stain I do get a bit but I believe it is from the floralicious plus as that is a very dark syrupy nute. All in all I have been very happy with my mix of remo nutes, adding side lighting, and this runs topping and defoliation methods. I will definitely build on these practices on future grows.
