For what it's worth, all is back on track - buds are getting pretty huge, but fluffier than normal. Some male flowers showing on one strain only (might even get some female seeds from it if it self-pollinates). Not something i'd like to repeat, though.
some new-fangled digital one...HPM - only just started using it, but must have got one of the programs wrong when i set it up. Worked fine for a week before. I'm using an old manual one now, the one with the push-down buttons on a dial.
Week 4 into flower and my timer shat itself, putting the light on for 24/7 for at least 10 days
It went unnoticed because i only check it in the afternoon (when the light is normally on) so didn't spot it until the buds went all weird and putting out veg. leaves.
It's been over a week, since...
