When do I start watering with no nutes?

It looks like some of my buds are starting to get red hairs on them! I've read that I should harvest the buds when about %70 of the hairs on it are red, and that you should use plain water in your reservoir 1 week before you harvest. My question is how do I know when it's 1 week until harvest and when do I put in plain water?

Ya really want to look at the trichs and not the hairs. The hairs do give you a heads up that it is ripening. How long have been flowering?

i personally like to just back off the nutes slowly and try to get at least two weeks in of just plain water..but thats just me

oh ok. i'll get a magnifying glass to check out the trichs. i wait till the trichs are %70 red before harvest?

oh nevermind, i just read SpruceZeus's article!
