Well, in the absence of any feed-back re. top-dressing with fairly minor amounts of gypsum and langbeinite with 3-1/2 weeks or so left until harvest, I took to the internet ... again....while drinking a beer and tending a smoker with a bacon-wrapped pork shoulder roast seasoned with minor amounts of thyme, garlic, white pepper, and a drizzle of honey, before adding the double layer of bacon to the top of the roast, pinned with wooden tooth-picks.. Made more necessary by the meat dept that took nearly 100% of the fat cap off the roast.. Ignorant bastards!!!
Anyway, it was in the midst of that, following the 9% abv brown ale that I said, "screw it" and mixed up a test batch of 2:1 gypsum and langbeinite.
If a guy's gonna' mess his plants up, he may as well be eating and drinking well, right??
Anyway, and being a bit more serious, I used 3/4 tsp of the mix to top-dress the WB, meaning about 1/4 tsp of langbeinite, and 1/2 tsp of gypsum. I believe when applying experimental approaches, especially better than half-way through flowering, it's best to tread lightly.. Though this application may be light enough to make very little difference.. we'll see.
I applied perhaps a quarter of that amount to a couple of mothers in much smaller pots last evening, and perhaps it's mere subjective perception, but I believe the H2O processing, (and therefore feeding/fert absorption) would appear to have stepped it up a notch or three; the one that was watered with the minor top-dressing (WB) is darned hear dry today...
I may be onto something.. or maybe -on- something.. but thus far, I haven't killed anything, so it's a decent day.
SLH's buds are improving in size ever so slowly, and still pungent and crystalline. WB is being her fussy self, putting out nicely elongated pistils, perhaps 5% of which show abnormal pre-mature darkening, thus the reason for choosing her as the initial guinea pig in this top-dressing experiment among the three varieties...
GTH#1 is still increasing in size, trichs improving daily, and the pungent nature is waxing and waning with the light and watering cycle.
Aside from those mysteries and experiments, it occurred to me the other day that it's been since last October or November that I last changed my Merv 8 pre-filter and carbon panels in the filter box, yet the area near the grow smells clean, despite the plants having a nice odiferousness to them when sniffind in the room itself.
Mysteries and questions abound.
I guess I'll check the smoker's wood supply, have a puff or two of GTH#1, and take a nap.
Any objections?
I didn't think so....
Moose,
If you saw a Mg deficiency, chances are you are missing phosphorus. Or you already have too much potassium.
