The buds are growing and so is the smell, although it's still not very strong. It is a sweet berries/fruity smell and it's very pleasant. The buds aren't that big yet, but she's still has time to grow and bulk up.
It's been hot here. Keeping lights out during the hottest time of day does a lot to keep it from getting too hot in the tent.
Overall she looks healthy. I noticed some leaves are curling down and a few have burnt tips. At one watering I accidentally added double the amount of biobloom and I think that this is what caused it. The next watering I gave her was only water. It seems not to be getting any worse. I'll keep checking on her for signs of recovery or getting worse.
The next watering I gave her nutrients again. A few of the pistils have started to turn orange.
Looking good, I need to get to the point where i can say "2 more weeks" confidently. Its more of a guessing game with the plants I've grown so far as there has never been enough really clear trichome changes, even harder to see on these purple varieties.
@eurorack, Thanks a lot! Just because I can say it confidently doesn't mean I'm right ;) There are other factors that also let me know that the plants are almost ready. They start to drink less water than before. Some of the fan leaves fade yellow/purple and some fall off. The pistils curl and darken. And the trichomes change as you mentioned.
