Sep 1: there might be a bit of lower leaf damage on WP1 after the 2 C night here two nights ago. Otherwise everything seems fine and the buds are progressing.
Sep 2: removed some yellowing fan leaves that had been damaged by cold temps.
Sep 3: WP1 has finally stopped getting taller and is starting to flower. Good thing too cuz the days get short pretty fast now and it will be iffy as to whether this plant will finish in time.
Sep 6: Well, I spoke too soon as WP1 is still getting taller, and it grew 4 inches in 3 days. This far north, it should be flowering not vegging by early September. Oh well. Lots of insect life on WP1 (ladybugs, spider, flys, few ants even) and a few aphids so it seems to be in a balance and the plant is fine.
WP2 in the city was force flowered a while ago and is progressing nicely. These are in small 5-gallon pots in an attempt to limit their size and to encourage flowering.
