I had a timer for whatever reason stop working about 45 days in for almost 3 days. The lights never shut off. They stopped filling out, potency was a huge miss and smell/flavor was different from many years of running the same cloned plant. This is just 3 days of not getting a dark period, yield was less than half of what I was expecting. This had a negative effect on finishing time and I ended up leaving them another 2 weeks before I figured that was as good as it was gonna get and harvested. EDIT I left them another 2 weeks passed the usual 9 week grow cycle is what I meant to say. Even at almost 80 days in they never fully ripened and again this was a consistent 60-65 day finisher.
Finish them. Been growing them for what, 3+ months now? Dont waste that time. Your seeds wont stink or need any intense light for weeks anyway, so you could still start them now if you have a window sill, small t5 led cfl etc. First week or so they could sit in the middle of a room and still sprout properly.
