I'm 100% sure Ive got a spider mite infestation and I'd like some help on how to kill them. I've heard that soapy water will do the trick, but I'm concerned that the soap will bring the soil's pH up to a dangerously basic level (maybe), so would you use lemon juice or vinegar to level the pH out? I've heard the soapy water trick from two different people, and neither said anything about adding lemon juice/vinegar, and you can always lower the pH later (acidify it), so I think I'll go ahead and do this...? Any suggestions? Comments? Feedback?
