Ph down

So my grobo plant that’s only on grobo nutes no supplements is sucking down ph down like water. Just added new bottle at the beginning of grow now its empty. Could heat be doing this. Why is the ph so off…

Nope, defiantly an issue your bottles 1 & 2 should easily last two complete grows. My best guess is a calibration required. Easy step by step process in maintenance but you’ll need 4.0 and 7.0 buffers to do it.

U got equipment to adjust before drain and fill? That’s what I did at first. Now I am not and it looks like it has used quite a bit more.

I calibrated before I started this grow.

I’ll try that. I’m gonna have to feed her and keep record all my bottles are empty. I’m not spend another 80 bux on nuts from grobo
