No nothing to the ph my tap water ph comes to a 7.2 with all nutes added its 6.2

If you feeding @6.2 what is your run off ? My guess is you run off will be over 6.5 ??????? If it is you will get a lock out !!!

My feed in to coco is 5.8 and run off is 6.0 and raises throughout the week so i have to water every now and then @ 5.5 to " reset it " back into the sweet spot

So my tap water ph is 7.2 once nutes added its around 6.2 and runoff is mostly exactly the same
