I think my plant in the front still has pretty immature buds in week 11. The two plants in the tent were planted at the same time. I planted both in the Living-Soil soil and added worm casting and dolomite lime a few days ago. More info in my diary.
Yeah, it looks like that, it's all about the genetics; some ripen faster while others take longer even though it's the same strain. The one in the last picture looks pretty ripe, and I think you can harvest it soon; almost all the trichomes look milky, and that's where it has the most THC.
The other one in the first pictures definitely needs another 2 weeks, just from the feel of it, but both look really great.
Just genetic variety...
for future reference... if it happens and accompanied by dead sugar leaves, inspect under buds for white/grey mold -- will look fibrous and impossible not to notice.
Since the plant is relatively healthy, it's just a slow flower. Will probably have a larger yield, too. It tends to correlate.
It could just be a different phenotype that's a bit behind^^ I wouldn't stress about it, the plant mostly decides for itself (genetics, pheno, etc.)
If they all get the same amount of water, nutrients, and PPFD, it's just a different pheno 💚
