I have been using Masterblend, epsom salts and calcium nitrate for growing hot peppers for years now. I use it in soil and this year I am also using it in a dutch bucket system I set up. Having awesome results.I'm using Masterblend and also use it for kratky jar herbs and houseplants too. I am adding Flower Fuel now that I am in flower.
I recently started using it on some white widows to try to correct a problem Im having with them.
Haven't seen any improvements yet but am curious how you use the Masterblend. Any different doses between veg and flower? Ive read several different internet threads about it and of course most are different.
Let me know. Ive got plenty of it around here.
