I had a couple extra plants left over in small containers after I put the keepers in big pots, so i used them to do a little experimenting and one thing I noticed is that, soil web or not, with plants that have outgrown their pots, it seems to me that sometimes there isn't enough soil and microbial activity to break down organics rapidly. I had three plants that had outgrown their pots and were all pretty identical. On one of them I stayed organic, and on the other two I started feeding with Veg+Bloom Dirty (A chemical fert designed for soil) and the difference is crazy now, the organic one is still very small while the chem fed ones are exploding. It is worth noting however, that I also have plants in larger pots that haven't outgrown the pots and become root bound, some of which are organic and some of which have been fed with the Veg+Bloom Dirty, and in the plants that have large pots, I see no difference in size or vigour between the organics and chem fed. So maybe in plants that have become root bound, when there is very little soil left in the pot and it's mainly just roots, chem can provide the nutes in an form that the rootbound mass can easily absorb while organics fail to be broken down and utilized due to the lack of soil and soil web microbial activity. Wow I really had trouble keeping that concise, my bad. I can post pictures tomorrow when the sun comes up if anyone wants to see that I mean.
