Wilma help please?

Hey peeps!

So I bought a Wilma 4 system, however... I adjust the ph of my water down to 5.8 and check the next day and it’s up to 7.2... any ideas what’s causing the ph swing? I have the normal pump with it as well as a mixing pump that’s on all the time, I’m growing in 60/40 goldlabel coco/clay... have the blue Drippers and feeding 2 x 15 minutes feeds at 1/4 strength (my seedlings are pretty young still)...

With what are you adjusting you PH with? Is the "goldlabel" medium cleaned and ready for use? Soak it in water for an hour and check ppm before and after that.

I’m adjusting down with Dutch passion ph down and I may of skipped a step with washing the gold label (didn’t have this issue previously when I was hand feeding on my previous grow... that’s my bad on that one :-/
