Smell

No smell isn't really a problem. At least no one will bother you cuz it's smelling in the hallway xD. I read somewhere that using beneficial microbes and sugars can enhance the flavors and smells of plants. Good luck friend.

Smell and THC levels are not related. Some plants don't smell very much and others start smelling much later on in flowering. Not to worry, your plant will be just fine.

I've found the intensity of the smell simply depends on the strain I'm growing... some are super strong, others are light and kind of "background" smell... I wouldn't worry about this! One thing I like to do on the weaker smelling plants is to rub the stem - the smell will transfer to the fingers and you haven't damaged the pistils or trichs... Nice looking grow! Good luck!

Bet if you touch your pistils with your finger then smell your finger you will smell the weed.

If you are a rare smoker, maybe your brain will be picky, but thx will stay same ;) it's all about terpenes. Some strains start to stink later, some has weak aroma. It could be related to your growing mistakes or just genetics. Have a look at this https://www.healthline.com/health/cannabis-terpenes#:~:text=Terpenes%20are%20naturally%20occurring%20chemical,or%20taste%20different%20from%20others.

It’s not exclusively indicative of the quality or strength but is very desirable, there are some strains like super skunk that have the smell bred out on purpose with no effect on strength.

No smell strenght has nothing to do with THC level. Just a low odor strain or phenotype.
