No its not something I would do in the long run, just temporarily until I get proper airflow and humidity under control. What I used it for was a unique situation and I think it worked, as it was the only variable. I believe a low dose wont kill the good stuff, and if I were to use it again Id probably add mycos mix to the next watering to fortify what may have been if at all injured.One explanation could be they were overferted or ph off, and this fixed it a bit so they were able to absorb some nutrients. I don't see it working in the long run, tho.
