How much longer?

They are into flower 53 days. Hairs are just starting to turn red. Trichomes seem to be clear. Is it time to stop using my Fox Farm hydro nutes?
Buds are fairly large, very solid, extremely hairy little yetties. Anyone know what they are?

WOW Those are some BIG hairy buds you have there!!

I would wait to start flushing. IMO wait until most of the hairs are red and your trichs are partly cloudy.

Check 'em out!

actually you are probably close enough that you can switch over to pure water. You want a good week's worth of flushing. You may want to wait a few more days. Just depends on the strain. For instance I do white rhino, and it seems to like 70 days of flowering... Once you've budded this strain a time or two you'll know exactly when to start the flushing process.. It's all a learning process.
