mag def.

I use 1 teaspoon per gallon, reason? because that's what I read on the internet. I also read 1 tablespoon and also 1/4 teaspoon, so you can see why I use 1 teaspoon per gallon. First comes mag then comes cal, all because of too much P.

I started noticing pictures of plants with lush green leaves but also mag def, and they were using a typical cannabis low N, high P middle K, so to get that much N they must be adding a lot of P. It's all there, just out of balance. Cal and mag are related, It's not the amount, it's the balance. Adding to the one def only usually causes a chain reaction of operator error. Flush and start all over 1/2 strength of everything is usually the doctors standard advice. In good organics, simply epsom can be all that's needed.

 

Foliar feeding is misting the plant leaves under and over, not the soil. Good luck
