What is it going into and out of???

Soil or coco? Or something else’s?
In at 6.5 im going to guess soil and I’d say it’s a little high an not really normal but, if the plant seems happy and healthy id take note of it and carry on as i had been.

I was watering my plants taking a pH test go in and coming out after I I watered. Fox farm soil and Fox farm Coco loco haven’t get my pH and TDS meter yet. Just trying to stay on top of things. Thank you

You’re in soil. Let the buffers do their thing. Just water between 6.0-7.0 and the soil will do the rest.


Thanks for info
