That could get expensive. Ruin a crop and still have to pay electric bill. Been there done that. Last thing i ever thought was my pH was off because of a pen going bad.

That would fn hurt...

Lucky for me, I haven't seen any obvious signs of big problems. What I have been noticing this run is that my flowers seem too small compared to where they should be at week 5 (I know this strain really well AK47). I've been blaming it on weak genetics up till now, (picked a bad mom) but in light of the funky pen discovery... I wonder if maybe my pen was out JUST enough to nudge pH out of the sweet spot for nute ideal uptake, but not far enough out to really cause serious problems...yet.
