agreed, I think in therory,the soil not needing adjusted ph outdoors may be true but I think when we are talking about growing in 1-3 gallon pots ( on average) that can only buffer so much, but I am pretty far away from being an expert. this grow has had issues almost weekly. I grew an ak plant last year with really no issues with out even adjusting my water. Iam glad that Im having problems right now because I have really learned a lot, just frustrating.
