Hello all. I'm trying to troubleshoot a matter that I've been encountering with my crops during the latter stage of flowering. I'm relatively new at this and only grow once a year on a very small scale just for personal use. So please pardon my ignorance, as I'm still very much in a learning curve. I've used Sub's recipe the last two years in a row and the plants absolutely THRIVE in it, except toward the latter half of the flowering stage. They first start fading about three weeks into the flowering stage. Very slight at first, but profound toward the end. At the same time the leaf tips start showing signs of nute burn, which gradually works its way up the leaf. Secondly the trichomes don't seem to reach their optimum potency in terms of cloudy vs clear. Some do turn cloudy, but a high percentage remain clear with little noticeable improvement over the last few weeks and days of flowering until I'm forced to harvest due to the plant fading out too much. I realize that fading is normal during late flowering. But the symptoms of nute burn during late flowering have me puzzled. Also, just based on the ratio of cloudy/clear trichs at harvest I suspect I'm not getting full potency. I don't know whether anything can be done to postpone the fading, or even if that would have any benefit in optimizing the trichomes. Also, to me it seems counter intuitive to add more nutes or top dressing to reduce the fading, when at the same time there are symptoms of nute burn. I'm using a 2x4 grow tent, two Platinum 300W LEDs, RO water only, Boogie Brew compost tea every two or three waterings. The grow tent and room are well ventilated and climate controlled. I only grow two plants at a time, each in a 10 gallon fabric pot. So overcrowding isn't an issue. The strains have been Barney's Farm Pineapple Chunk and Liberty Haze. Maybe it's the strains, not the soil...I dunno. Any helpful advice is greatly appreciated. Thanks in advance.
