Sup fellas. I'm going at my second grow as I'm new to this. I'm only a month and some days in and i had to give a plant support. The stem smells of weed. This morning when I went to check on them, the smell greeted me. My first grow didn't smell why? Strand?
To answer the first question, even though it has been done, it comes down to genetics. Some strains become fragrant earlier than others. I had one recently that about 3 weeks in started smelling of key lime. It was awesome, but the profile changed in flower. Damn, that would have been awesome too. lol
Your second question was also well handled. They need more light. A shitload more.
