Sep 12: getting close to the end but not quite ready yet. Unfortunately there has been five or six nice colas hit by bud rot. I check it daily for any brown and shrivelled sugar leaves and I found a disturbing number today. Was only 4 C but with 90% humidity last night which explains the bud rot outbreak. Will try harder to keep it drier. With that, I decided to do the Final Flush today. Started using this last year and I quite like what it did. A few years ago I had buds that didn't burn properly and that was due to too much P fertilizer. This flush uses citric acid to chelate the salts and remove them from the soil. Good stuff. Sep 13: did another 18 L flush because I decided the 9 L flush yesterday wasn’t enough at just one pore volume (30% of 27 L of soil). Defoliated to improve air flow and sunlight to buds. Sep 16: the bud rot is systemic showing up in 16 colas at the same elevation- about 5-10 cm below top. I think it was due to one night last week of 4 C and 90% humidity for about 8 hours overnight. Harvested the top buds to keep it from spreading further. Harvested 625 g of mildly immature buds and threw out almost that much - leaving the lower buds to mature. Clearly I spoke too soon when I said ‘one pound no problem’ a little while ago. Great fresh chemical smell tho. Fresh frozen to deal with later.
