I dont know if this will help or not, but as an example, my DWC plants are on the Biotonicare starting at 1000ppm and looked like they were in a nute lock/def, i increased to 1200ppm and they did a nice improvement, almost immediately (within 24hours the ppms dropped 200), so i upped it to 1400ppm and the samething happened, almost immediately there was another nice improvement (24 hours later 100ppm drop) so i have just changed it to around 1600ppm and they are now getting the rich dark green leaf and bright center.... coming together nicely, but watching that nute drop for me was key.
