So I have a cheese hybrid plant that is showing a magnesium deficiency. It started with yellowing veins. I foliar fed the plant with 1tsp per gallon of epsom salt. I thought it was getting better because I didn't see any signs on the newer growth but now some of the veins are turning brown so I think it's getting worse. I had another strain in the same soil that was showing the same problem and I foliar fed that one and the problem stopped no browning on the veins looks good now. I think my soil is deficient in magnesium. I use Spartans agricultural lime because that's what my local hydro store offered it's 30% calcium and 3% magnesium. My question is should I start watering with 1/2 teaspoon of epsom every water now to supplement the low magnesium in the soil?
