Its still got to be withing a respectable range though but like @George has stated his supply is 7.5 from the tap and he has no issues.
i’ve been reading this forum for a few months now and have been wondering what all the hype about checking the ph was about. that was one thing i never did, or ppm of anything. i was almost wondering if weed had changed that much that it was all of a sudden sensitive to it now.

It’s medium dependant
DWC and coco need adjusting (unless you use ph perfect)
Most soil buffers ph so not needed.
Easiest way to grow weed is buy a super soil and just add water and the odd nutrient tea every so often.
People grow in dwc and coco for the increase in yield but like we can see with this thread it has its disadvantages.
