My first grow -autoflower - indoor

Tl;dr: My plant seems back on track, heading into it's final phase before harvest. After a tricky week with leaves turning yellow and exceptionally adding some nutrient, I went back from about 1l/day to 1L every 2-3 days. I'm 90% sure it was an overwatering issue with the leaves looking a bit better, but most importantly: not getting worse. Luckily this did not affect the growth of the flowers much. In week 9 the buds got bigger, forming one big cola on the bigger branches. All of them have white trichomes on them and halfway this week the first pistils started to turn brown. The plant is clearly putting it's energy in the flowers, with almost no change in length or branches and leaves. Overall everything seems to evolve as it should be. I'm expecting to grow for at least another week (10) and probably harvest in week 11 once the trichomes turn amber. As for smell: you can smell the plant in the tent, but in the room or the room next to it there's no scent at all. There is however an important caveat: I usually have the charcoal filter to around 1/4th-1/3rd of it's max power (The filter that came with the Mars Hydro tent can do 200 CFM, but that's overkill for one plant in a small tent). This afternoon I wanted to test the difference if I lowered the power of the fan (to cut down on the noise), and about 2 hours later the hall next to the grow room had a very clear weed smell. Important detail: this was right after watering, so humidity was very high afterwards, probably partially causing more smell. I repeated this a few hours later and the scent seemed less intense. I admit this is not really scientific, not even sure if it's different, or I just got more used to the scent. So setting the filter fan at the right speed is crucial to keeping the scent under control, especially when you can't have a window open all the time. But knowing that the plant is well in it's flowering phase, it's still a relatively light smell. Next update will take at least a week. Hoping to see more brown pistils and keeping an eye on the color of those trichomes in the upcoming week. Very curious if the buds will still continue to grow.
