I was doing similar, not near as many foliars but definitely doing some supplemental foliars to fight low ppms, it helped but was a bandaid, being Rootbound was a constant struggle of low ppms...once settled into bigger pots and with a simple top dress they are all praying before the lights even come on!! Will check slurry before next feed to verify numbers even though the top growth is telling me their on point, Bubba likes to call these preventative slurries, and they are just as important to do as it is when troubleshooting. This slurry will guide my transition feed and will tell me if I need to keep alternating double feeds or just get back to regular feeds....we will see, I'm very pleased so far but it could have all been avoided with a repot at the correct time....got busy, life happens!!
