Given up running a grow log here. Moved to reddit
In case anyone wants updates on this grow, I've moved the log to https://www.reddit.com/r/fubargrow/ for posterity.
Long story short: One male culled after 10 days of flowering. Strategic defoliation at about the same time - I really wish I'd done that much earlier.
Two girls left - one a very, very stretchy plant that has gone from 10" to about 23" and the other from about 9" to 18". Both still gaining about an inch a day at the start of the third week of flowering. Will need to replace the reservoir with something less tall to keep them from hitting the tent roof at this rate.
