Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Living soil and rain water problem Has using rain water killed my living soil? Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients. So basically is my living soil now just soil or is the microbial life still there?
