Who told you that strain had a 5 wk flower time or 42 day? Most I know are atleast 60-65 days considering you dont start counting at 12 12 flip even longer if that's what you're going by " light cycle ". Most go by plant cycle they dont immediately go into flower upon a 1212 flip so you cant say they are in flower. Have to wait until new growth stops and buds start forming, that's flower. Generally add about 2 wks to all flower times give or take a few days
Good job so far, rough estimate you're in mid flower, you feed them right you'll have some fairly large buds, excellent stacking imo
