Thoughts? pH 5.6 in 6.6 out last watering

I get high ph runoff sometimes. I'm not entirely sure what causes it but if I use some enzymes or peroxide it usually fixes the problem. How is your ec runoff?

I don't have an EC meter yet unfortunately. That will be one of my next investments.

I think you should be ph’ing 6.3-6.7. If I watered at 5.6ph.. I wouldn’t be surprised if any issues surfaced.

Ok. I was only doing that because historically my pH levels have had very high runoff values, consistently 7+ and as high as 8.5. I have been watering in the 5.5-6 range to bring it down, and just recently it has started to stabilize. Thoughts on this? From this point on should I water at 6.5?

What is your medium?
don’t worry about runoff ph and focus on getting an accurate EC meter. To test what your putting in and what’s coming out.
In soil don’t worry about ph if your using tap water just water normally and don’t water to runoff in soil because your just washing all the food stuff out of the soil.
Give some more details about your grow if you can
1.medium type
2.nutrients and amounts your feeding
3.temps and RH
4.how often do you water & how often do you feed
5.how much water do you give & how much runoff are you getting each time

Some solid advice you’ve been given here! Don’t chase your runoff with soil. It can lead you in the wrong direction and I wouldn’t water to runoff.
