Hah! I love those little jumpers! Too bad they eat the beneficials, too, but I guess that is nature, and I'm sure not going to remove or kill them.
I'm taking your advice and resorting to using some ionic nutes (Megacrop and Bud Explosion is what I have on hand). On these two plants. They were only ever experiments in organic growing. When I mixed the soil, I put in mostly promix, and only maybe 10-15% of my super soil (those are big pots!), and then I planted immediately. It got the plant this far! Top dressings have helped I'm sure, but these are hungry plants and I'm not going to let them crash. So, hybrid organic/salts it is!
My plan in the off season will be to either convert these into worm bins, or to create a no till living soil in them. Adding more microbes and some more organic inputs. They were just never given adequate time to grow a proper micro herd before being planted in.
Thanks again for the help, Waira! I appreciate it!
