I would look at your (hard)water before anything else.This will cause nute lock out(PH)problems faster than anything else.I use FF-OF soil and every other watering add a 1/2 teaspoon of epson salts to my mix.Some (white) varities use lots of MG. so for them I add a little more.Using bottled water will generaly be a better choice.In Phx.Az. they have R/o water outside of our supermarkets-25 cents per gallon if you provide the container.Sweeeeet! |
