m0useanswered grow question 3 years ago Some companies offer steps on what to do if it goes beyond the suggested feeding length.
eg. repeat weeks 7 and 8 till harvest or repeat week 7 till harvest if week 8 is a flush.
If you feeding regime has a flush step and you use it, I would keep feeding its last weeks dose right before the flush and then do the flush when you feel its ready, if that's your thing.
I myself do not flush end of life, just if theirs a imbalance of things.
Best to check trichomes as a gauge on how close they are to being ready, pistils are another indicator.
Can use both in tandem if you want.
Good Luck!
