@JM> No, you're all good, JM. No worries. That's odd though, because ph water and nute feeds have been going in at around 6.4-6.6 and run off has been 6.1-6.4 the whole time. As far as I know that is dead on, could it be something else? Well of course it could, haha. I dunno, it isn't real bad and hasn't gotten any worse I don't believe.
@Growbee> Yep, as stated above ph has been dead on, and I calibrate my pen regularly. Hmmm. I mean I noticed them and kinda thought it was bleaching since I had been having that problem before, and knowing that my ph was on. No heat problems.
