MBE(?) This grow I have been using MYKOS brand mycorrhizae ( man I hate trying to type that lol) if that is what you are referring too.
I will alter my use of softened water.
I neglected to mention that THESE plants have only received water from a 130 gal tank I use to over winter my shubunkins in the basement. It is filled with my softened water, however it has been sitting and being filtered by the pond filter. No chemicals. Just fish and lilly pads. HOWEVER I’ve done this in the past and had the same issues and I’ve used my strait tap softened water and had the same issues ( except outside as stated)
I would think it’s about time to top dress, I have Gaia Green 2-8-4, worm castings and mykos I was going to add soon.
I have epsom salt and cal-mag.
Thanks Mr Numb

Edit: I’ll see if I can get a water report. Our local well water is very high in iron.
