Hello.. Hope you are well..
@61days in i wud say she's got roughly 2wks left till harvest... Her pistils are turning brown but ur best chance to see optimum harvest time wud b to check her trichs with a x60 magnify loop.. This will help u to see if her trichomes av turned milky /cloudy and this is wen she is at her peak cannabiniod production.. Most ppl like most cloudy with a few amber trichs.. Essentially, the more amber trichomes thier are then the more couch like effect u will experience with her.. Harvest wen mostly cloudy and u will get more high(obviously this range expands up and down thru dif strains).. Stay safe n gud luck on ur nxt grow.. 👍🍀
