The only nutes i've been using is pure blend Gro....2 1/2 teaspoons per gallon. (I've read a lot that the PB Gro is a little weak, but i am using the amount recommended). And at my last watering I mixed 1/4 teaspoon of Bat Guano to the water, and watered them with that to try and offset the Nitrogen Def.

As for the lime, no i haven't added any of that ... and honestly i dont know what that is or what it does....do i need to?
