Hello. Here’s my opinion on this and why.
Option A: Harvest now (J77-J80) — Not recommended
If you harvest today, you will have a very cerebral "high" effect and a bit anxious because the plant is not finished. Most importantly, you will have finished drying before your departure, but you won't be there to monitor the start of curing (jarring), which is risky for mold.
Option B: Wait until J94 and dry during your absence — My recommendation
This is the wisest strategy for final quality.
Maturity: At J94, you will be right in the harvest window of the breeder (J80-90) plus a few days of buffer. The trichomes will be perfect, with an environment of 10-20% amber.
Passive drying: If you cut the whole plant (without separating the branches) and hang it upside down in your box (fan off, just the extractor on low), drying will take about 10 to 12 days.
The timing: You will return just as the branches start to "snap," ready to jar. That’s ideal.
Why are its leaves dry?
In image 16, you can clearly see that the plant is nearing the end of its life. It’s drawing everything it can for the buds. This is normal senescence. Don’t worry about the dry upper leaves; it’s a sign that it’s ready to take its last breath. Have a good day!
