Yes dyna gro is a liquid form nute. My idea was to use a cloner at first, but switched to soil. Theyre plenty old for nutes, almost a month now. I just think I underestimated the nutes in the mg to start off. But I have since flushed the soil and they are still lookin healthy, minus a few leaf tips. And I have about another week before I need to upgrade to the 3 gal bags. Ill probably buy a bag or perlite since Im completely out. I still have some mg and vermiculite, as well as peat.
