Any advice on a ratio to top dress epsom salt? I've got some ladies starting out in my own organic soil, recent switch to RO and I'm not sure if I supplemented enough Mg source so I'm looking for a premeditated measure. I can maintain with foliar feeds if I had to but I'd prefer not. Unless the general consensus is that fine dolomite will have enough mag. All help is appreciated!
Went ahead and mixed 2 cups of dolomite lime to 2% magnesium sulfate (1 tsp. per cup). Applying 1 tbsp. per 5 gallon pot. Another tbsp in early flower.
i wouldn't do that. if i have a mag def. i just water once a week with 1 tbsp. of e.s. per gallon of water.
