So I've been watering my plants with rainwater for the last month or 2. I never PhD it because I assumed it would be okay (when i at nutes to the mix i ph to 6.5). I tested it yesterday and it's around 5.0ph, i thought it would be fine considering if it was to actually rain on them i wouldnt be able to change the ph but now questioning whether thats too low and i should add ph up? Growing outdoors for the first time, any help would be hugely appreciated
