Ph issue

[leafy1986]

Hi guys. I've just calibrated a ph pen then watered 2 of my girls with 6.5oh water and runoff was 4.8 on one of them and 4.8 off the other. This is the first time I've tested ph is that normal.

What is your grow medium? Do you have any pictures? Is the plant having problems?

One of them has nute burn the other is really healthy. The one with nute burn had 4ltr flush with 4.4 runoff the healthy one had normal 3ltr flush with 4.8 runoff this is the first time I've checked ph. My 5th grow and same medium with all 5 grows. Never checked pH before and always done okayish last grow 209g off 3 plants. All been autoflower.
