Every plant In flowering room changed smell in few days. I have a mix of sativa and indica dominant strains (just this grow usually I go for same strains to finish together) so some are in the last week or 2 weeks of flo, and sativa doms are in their last few weeks.

Smell is suddenly more grassy and a bit like garlic on all of them, what could have changed the smell in all of them. Ive checked for bannanas and there is no, just one nanner seed from all the plants.

Not enough details to say with any certainty.

What is your day and night temp/humidity?
What stage of flower are they?
What's your air circulation situation?
What do they eat and how often are they fed/wattered?

Terpenes evaporate due to their low boiling points, which are typically lower than other compounds found in cannabis or other plants. Factors such as temperature, air flow, and surface area can all influence the rate at which terpenes evaporate such as your grow environment for them.

You got pics ?

If everything changed smell at same time I’m suggesting it may be something to do with your sniffer. Basic troubleshooting. Good luck. Do all the stem rubs smell of garlic and gas?

Sniffer is 10/10, situation is improving after thorough watering, smell is better again, must be cause of underwatering aa the leaves were saggy

I'm not real sure how I should explain it. If you like reading you could check this out.

Understanding VPD and Transpiration Rates for Cannabis Cultivation Operations

This article explores how vapor pressure differentials (VPD) affect transpiration rates in cannabis plants. Understanding of VPD at different temperatures and relative humidities, and its effect on this process, is important to gain maximum plant growth.
www.cannabissciencetech.com
But most seed companies and grow tent or accessories companies have articles that touch on VPD as well. Humidity measurements are relative to temperatures and if you increase temp you need to increase the relative humidity to maintain the same VPD. The stomata are like pores in the leaves that they breathe and transpire through. When it's too dry and to hot the stomata close up to try and conserve water so not to dry out and kill the plant right away. One biological function that indoor cannabis growers will benefit from knowing just a little about it.

Humidity is relative to temp. The hotter the air, the more moisture it can hold. If you raise temps, without raising humidity, then the humidity drops.
