Good question. I wasn’t sure so I did a little research. Here’s what I found: “HHC is a minor cannabinoid; it occurs naturally in cannabis, but in amounts too small to make extraction cost-effective.”

Which generation though? Are you looking for info on just the mother and father of the F1 or are you looking for explanations of characteristics for parents on all generations? I think it can be difficult to do this in large breeding operations.
Are you sure they didn’t mean 10 weeks of flower? Hard to tell you if water-only is fine right now; the last pic you posted a half month ago looks like the plants had several more weeks to go. How do the plants look now? Got an updated pic?
Sorry for the delayed response; I was away for a week. Looking at their condition and seeing many of the leaves already faded or mostly dead, I think you’d be safe keeping the PPM 1000-1600 until harvest.
