Sorry to hear. That's always a bummer...They are much bigger plants than I thought from the first pics, so you've done good anyway. Stems look a little woody perhaps, which can be a sign of problem, but generally they don't look bad. Not very bushy though...which makes me wonder what sort of pruning you've done.
They look like pretty big container. Are they in dustbins?! (garbage containers...if you're american!). If they are then make sure they dry out properly between waterings as they could hold a lot of water at the bottom...! (sometime having too big a container makes is difficult to know whether the bulk of the root-ball is in the dry or wet part of the container!)
Also..when you say 6 weeks since flowering...how sure are you? Outdoors plants usually have localised end-dates (e.g Late Sept in Northern Europe), rather than flowering periods (which is for indoor plants, where the change to 12/12 is sudden.) Each variety actually starts to flower at slightly different photo period. Many will start to flower at 13/11, or even 14/10...but doing 12/12 guarantees that 100% of known strain will flower...so that is why everyone goes 12/12.
Outdoors, where the photoperiod changes slowly flowering is usually longer than with indoor grows.
