If you go by days and not actual plant maturity , ide say thats less accurate then carefully watching it mature.
Im a newer grower myself, so i know its difficult the first time around to judge maturity. I use the breeders dates more like a ruler to measure my plant against.
When the trich’s turn to frost white its very noticable, they become almost shiny.
Apperantly this is when they are most potent, i chopped mine as soon as i noticed peak frost was beginning to wane and it began to get alittle more soft or tan.
