Farmbuck, from what I have seen here, you clearly have a deep understanding and grasp of what you are doing and I almost feel silly offering any advice to you at all. I'm not sure why, but for some reason since I began using my own homemade living soils I have had virtually no pest or PH problems with my grows. This is my third season running my own soils and the results have been exceptional. I know you grow indoors and many who do often balk at bringing it inside but I do it often when one or two of my plants needs special attention and I've never encountered a problem. Before I began this method I often had to battle fungus gnats, leaf hoppers, root aphids, and such, but now, nothing. By far the biggest advantage has been not having to chase PH fluctuations every feed. The living microbes and enzymes they produce have literally kept my soils balanced within a tick or two from optimal. Anyway, I may be preaching to the choir but I just wanted to give you a little food for thought. Keep up your exceptional work and sharing those beautiful pictures.
