Hummm, I have a strange thing with my flowerpot. I have not used it since maybe 1-3 months. Yesteday, I vape with it and found the vape a little bit aggressiv. It milk faster and harder than what I remember with exactly the same glass and same way to vape. I decrease the temperature by 2°F and after by 5 and finally by 10. My old spot was at 523 and now I am at around 470 a. I am a little bit confuse.
Besides the things that others have suggested, I wonder if it could also be from using different material, grind or humidity and cure level?
Something like that might also happen me with a clogged or oily screen, a higher water level, or if I just get lucky and load it a bit thickly in the right places. Any extra restrictions will slow draw and increase clouds. (Does your Flowerpot contain balls that may need cleaning?)
Dusty stuff with lots of kief can also do it.
Maybe you were holding the head on the bowl a little sideways before, or had another slight air leak, or indeed a slightly loosely fitted coil in head would explain it, as it might easily happen on these.
Perhaps our lungs get slightly stronger or weaker at different times in our lives too!?
I recently fine tuned mine about 7 to 10 deg. Celcius, I think different material and humidity level of material play a big part in this.
And some strains and quality materials can give bigger clouds..
