I've actually, very carefully removed two plants from the soil completely. This was because I had used slow release nutrients. I used a hand full of Miraclegro when I initially mixed the soil. The plants were auto flower Amnesia Haze about 8 weeks old and were entering flower stage. The problem was at that stage the plants don't require the Nitrogen but all that Miraclegro was still in there. Both these two girls showed signs of Nitrogen toxicity. So I very carefully removed the whole block of soil from the pot. Gently broke apart the soil the roots held together.... Though I probably could have just used a spray bottle to remove the soil. Mixed a new batch of solid. (Potting soil, earthworm castings, Perlite and Mykos for the roots). And replanted. These poor plants went through hell. Knocked over by my cat when one was just a week old or so. Bent and kinked in half. I supported her and she actually healed and became pretty damn strong in the end. They also had a spider mites! I caught it sort of early, bathed them in dish soap.. Killed the mites. But I'm sure all this reduced the potency. Still though. Pretty good smoke in the end.
