Do I water a week before harvesting??

Continue with ph water only for last 2 weeks. It is called a fade. Allows plant to use up stored energy, color morph if it will, makes end bud taste better. Unless you like smoking and testing fertilizer. Very bitter and harsh when I tested it, rather gross. Me personally I do last 2 to 3 weeks. Once my buds stop beefing up and cloudiness is starting good in trichromes I flush the ph water till finish. There will be deficiency signs etc. In this process. This final stressing plus darkness I personally always do.
