Not quite, my assertion is that flushing could help raise THC levels in crops that were fed excessive Nitrogen,
I don't know what "excessive N" is. If you feed a plant too much N it will burn some of the plant matter like root hairs, show up as leaf margin/tip burning, margin cupping, etc. and in general stress the plant and compromise its vigor and health.
Flushing is another myth, now a paradigm with some, that started with the Dutch in atonement for them burning up their plants by applying too much salts. A plant is not a radiator, it does not flush. Leaching the soil aka "flushing" does nothing but deprive a soil borne plant proper nutrition.
2nd, I don't care what people say, especially in cannabis gardening forums. Again, I will take care of a plant's nutritional needs until harvest. I know what plant unit drives production and that includes production of cannabanoids - it's the leaves. I do know that buds tend to have a crispy, a gritty feel, when plants are fed with the typical low N bloom foods.
Lot's of caveats in that study beginning with the plant material tested -
1.
Kompolti Hibrid TC - This high-fiber variety has a THC content (0.5-0.7%). . Seems to me that testing nothing is nothing.
2. Table 2 shows that plant mass more than doubled with the higher amount of N,
228%, while the THC content of the leaves only decreased 18%. That may be significant to a farmer dealing with the law, but not regarding smoking. You just smoke a tad more to get the same high. Again, if you're damn near the legal limit for THC production regarding your hemp genetics, than I guess one could agree that this is a "significant reduction in THC" plus the bonus of producing a lot more fiber which is the goal of a hemp farmer - production per acre. Still, seems to me that 18% of nothing is, well, 'nothing'.
3. They never measured flowers, only leaves which doesn't make sense to me unless they're focused on the fiber found in leaves -
Plants were grown until the end of flowering for staminate plants. Leaf samples were collected on 13 August in the following way: every leaf of both the staminate and pistillate plants was collected, dried at 40�C for 24 hr, ground, weighed, homogenized,.....
Also, you pounded your chest regarding the "he saids she saids" and that's OK. I'd like to see photos of your garden in order to get an idea on the health of your plants, please.
Sidenote - it's high levels of P that induce stretch.
Interesting study fer sure!
