On my second grow, and so far everything is looking good. Not wanting to make any mistakes, I have a small question about watering. My PH is at 6.2 to 6.3 in the jug. However, testing the runoff it's 5.5 to 5.7. Do I want to increase the PH in the jug (before watering), so the runoff PH is Higher (6.2-6.4)?
