These are the results of the first Ocean Solution 203 experiment that I have done. These results do not say much at all about the OS 203 product, but it seems that the combination of 1000PPM MasterBlend + 400PPM Ocean Solution 203 was not favorable to the plants.
In the next experiment, I'm going to try 1400PPm MasterBlend in both growboxes and add 400PPM Ocean Solution 203 to just one of them.
Minerals are an essential part for an optimal functioning physical system. Any lack thereof, finally results in some form of negative effect.
