When do you stop nutrients?

When do you stop nutrients? They have been on 12/12 for just over three weeks now. Assuming 6-8 week flower time. What do you think.

Growing white widow/blueberry.

I know that you want to flush with clean h2o about a week or two before beginning harvest, but not too sure exactly when to stop flowering nute feeding. Good question!

Good question. Tomorrow is 6 weeks for my girl. Pistol just started changing colors.

nice..you can go by the pistils coloration to determine peak harvest time, but its better to get a little pocket microscope and judge by the coloration of the trichomes.

Everywhere that Ive read on here says stop the nutes about 2-3 weeks before harvest.

you stop 2 weeks before harvest, and feed only water. it is also a good idea to flush with water or a flushing agent during the flush. not sure on the finishing time for the strains you got, but usually purty accurate, and you can fine tune if not in later harvests.

White Widow is an 8-9 weeker. If you chop it down at 6 weeks you are going to miss out on some bud. Plants can put on quite a bit of weight in the last 2 weeks.
