my "technique" consisted of planting new clones in fresh pots of new soil and watching the ones in the kellog almost immediately show nute deficiency, and slower growth.. i could have fed the plants more to eliminate any deficit, but you shouldn't need to fertilize brand new dirt.
not to mention the mushrooms and thrips..
I'll never buy it again, and I'll continue to tell everyone who grows to stay away from it.
glad it works for you though... keep growing the dank brother
