Hi All, After a bowl or two, I’ve been thinking about some experimenting. Here’s what I’ve got: Hempy pots with straight perlite, fed 3x a day (at lights on, 4 hrs later, then in another 4 hours) automatically from a tank of mixed nutes. And a quest for less nutes in the finished product. The plants, in the second week of flower, are currently getting fed 840 ppm at 5.9 pH and I’ve been checking my runoff water and seeing about 500 ppm and 6.1 pH coming out. During my quest for knowledge, I came across this chart and variations of it quite a few times: Based on this, it appears that I need to have a little wobble in the pH to have access to all the nutrients. I could start at 6.2 and add a little pH down every day to the nute tank so that by the end of the week, the pH was around 5.6. Hmmm. More work… Something Useless said in his GH 3-part nute thread: “There are a couple factors that cause your PH to drift. The most common is running the nute solution too strong or too weak. If it's too strong, your PH drops. If it's too weak the PH rises.” I understand that he was referring to nutes in a recirculated system with his statements, but isn’t a Hempy bucket basically the same on a smaller scale and timeframe? What if I fed with nutes that were just weak enough to intentionally cause a rise in pH from 5.6 to 6.2 in the Hempy pot over the course of 4 hours, and repeated this 3 times a day? Would this kill two birds with one stone, or just my yield? So have I had too many bowls? Or does this sound like a worthwhile experiment?
