I was actually going to put an addendum, but I suddenly remembered that I have a job and had to run. ahem, "Then again, this is a vigorous, healthy plant. If it's a male, might be time to try making my own seeds."
Whorled phyllotaxy aside, the stem girth is absurd on this plant. I'll get a pic this weekend, but the stem on a 6-inch plant is thicker than the 2-foot sativa in the back.
I've heard of them, and have even read the page you referenced I read a lot of GrowWeedEasy before I discovered that OG had returned. Anyway, right now -- knock on wood -- all is going pretty damn well. I've got some minor deficiencies on a couple of plants, a rapidly-dwindling fungus gnat population, some plants that hold water too well, a couple where the peat seems to have gone perma-dry...
But these are workable imperfections, and I'm trying to address them by listening to my plants instead of working on a schedule. Organic is hard.
Anyway, new growth is vigorous, and almost universally healthy. As said above, the Chemdawg x Sunshine Daydream -- I think -- is dealing with some magnesium deficiency:
Lightening between the veins, almost exclusively on old fan leaves. I'd also guess that it's approaching potbound, which doesn't help.
Back to to broadmites: the leaf damage seemed to follow an extremely specific pattern, both in symptoms and in emergence. The bleaching on new growth, for example, was always triggered by watering, particularly when feeding. It's almost as though the plant would have a growth spurt and forget to color in what it grew.
Upon moving to the new tent, those symptoms disappeared in a few days.
So, I think (and reallyreally hope) that I don't have mites because they would have come along for the ride to the new tent, and I'd probably be panicking. I'll give them a good once-over to check for insect-looking leaf damage, but the majority of the leaves on all plants look healthy at this moment. Thanks for popping by, and if I'm wrong and flipping out in a few weeks, I'm taking you up for that eradication advice
