You could try taking your lighting time down to say 11.5 hours on, which may speed up the finish a bit...

Peace, Farmer Rich
yea actually they been on 12 12 for around 18 weeks but didnt flower for the first 3. I have a 30x microscope the trichomes are looking long with bubble heads but they are clear. I was thinking they have a long ways to go too but shorting the darkness sounds like a great idea. make em think they are running outta time I like that thanks. Do you think i should start feeding them again or keep flushing? These things could end up taking 20 weeks couldnt they? :/ pure sativas are a tough grow...
