Hello! How much can the plants have left? They are now about 60 days old. One of them seems to be a little behind. There is much less brown fiber. The smell is barely there in comparison. Not very intense. Lemon skunk
As others have said, about 3 weeks or so to go.
When there are 98-99% brown pistils (hairs/fibres), you will be entering the harvest zone.
All plants are individuals and some are faster or slower than their companins.
At least 3wks.They may not be ready at the same time as some strains will show a number of different phenos.1 may be like its mother and the other like its father.
