pH effect of Neem?
I've been using a neem solution to work out some minuscule bug problems I have (each localized in different areas of my house) and suddenly one of my tomatoes gave up the ghost. I've had a consistent problem keeping the soil moist enough for two indoor tomatoes that have been growing happily all winter. Could the neem oil affect the pH balance and upset the plant that much? only one of them is reacting negatively, all of my other plans are happy as they can. What is the usual season lifespan of a tomato plant? is this one just done?
specifically, though, I don't have a soil test kit. Has anyone using neem seen changes in balance during treatment?
