At this stage in the game it's kind of risky. You'll probably be okay if you clean up dense foliage and keep the airflow high. You'll have to decide if it's worth the risk though.
If your area is just going through a ridiculously humid period, I'd chance it. If your area has a normal environment right now, I'd invest in a dehumidifier. You might get away with it 5 or 6 times and then have issues and lose a crop. Is it worth the risk?

The higher your RH, the lower your VPD (if everything else stays the same). I found this, "if Vapor Pressure Deficit is too low the plants can’t transpire. Moisture may build up on the leaves, and the plant will grow much more slowly. If this goes unchecked for too long, the plants might get attacked by molds and fungi, like powdery mildew." You would need a very high temperature to achieve an optimal VPD at those RH levels. Depending on current temps, you may add heat?

I defoliated the and re-scroged it today also which raised the RH a tiny bit due to the release of humidity from the inner plant but didn't expect that forsure. but the high RH I've noticed since last water so I gonna let her dry out a solid bit before next water. Foliage on one plant is extremely dense and very premature compared to the other 2 plants, will rework them again tomorrow to help combat this issue I guess?

How much time could it be until the plant is ripe?Looking at the image of the trichomes (and ignoring the little black lint xD) can someone give me maybe a rough estimate on how long they could still take? Could it be a week, could it be 3 weeks?
I feel a bit unsure because I already see some amber ones too.

I got to harvest in 14 days: in order to have enough time to cure it before leaving home for 2 weeks (safety first: is a period of floods in here, I just can't take the risk). I had a pretty long vegetative stage but I'm gonna finish it at 13 weeks. Am I gonna ruin it it, right?
