Spring-Summer Second Run Mixed Strains

Chronicle of the Week: The week has been dedicated mostly to end of cycle management, which is not that simple for multi-strain cultivation. In particular, it seems that the decrease of the temperature affected sensibly the end of cycle. I already started flushing the plants closer to harvest (day 45): - Wedding Gelato - Dos Si Dos 33 #1 - 11Roses/Golosa "Orangy" Today (day 49) started flushing of: - Tangerine Dream #2 - Dos Si Dos 33 #2 Some plants start flushing during next week, probable candidates: - Glookies - Jack Herer (this one needs additional checks, flushing could be delayed a bit) During the week (already started the previous one though) I have seen some brown leaves in the plants closer to harvest (check my recent question). The answers I got so far are inconclusive (some say start of botrytis/but rot possible, some natural end of cycle fading). I tried to check closer the bud (they are very dense and rocky, not easy), I did not see anything worrying, although I'm not an expert on that. It seems that the brown part stops at the visible part of the leaves, the connection of the leaves are green). I added some picture of the brown leaves, taken with the microscope (not sure if it is possible to derive something, the quality is what it is). I decreased a bit the PPM by decreasing Calcium (since it takes some time to be effective, it is probably no longer needed, with the exception of the HBs) I'll probably harvest the first 3 plants this coming weekend (Wedding Gelato for sure, check again the other 2).
