so if its not one thing its another, ive got a few questions for you guys . so the tops of most of my girlies are starting to wilt . i know my temp is ok right around 65 cirq is good to so im asuming my problem is in the soil. i think the roots are starving for o2 so ive been adding c202 and vit b to the water .(is 2 1/2 tsp per Gallon enough ) so the soil i used wasent the best but it was what i could aford at the time .(this is a very low budget garden ) so the girls are about a month into flo and i was wandering if i switched the soil to better stuff would it hurt the girls that much. also what is the best (meaning free) way to take care of mites and little flies .
