Sensi skunk fem

So exactly 12 weeks old today I’m checking trichomes every other day atm as there still clear!! Hopefully another week of feeding nutrients then the flush before harvest! Still happy for my first grow! The girls scout cookie auto plant has been impressive and the bcn critical has also grown steady!! Leaves are turning more yellow and bud hairs seem to be curling over more each day which is a positive! Feeding every two days, trying to starve them as much as possible! Do I reduce my light hours in the last two weeks of harvest???
