They look great, especially for a first grow man!
As others said, some pics without the blurple light would give an even better idea of how your doing.
Also agree to go easy on those nutes, especially the Cha-Ching. I only used that stuff for the last 3 or 4 weeks of Bloom. It's potent shit.
And as to your smell and bulk question, both will increase throughout the grow. How much depends on the strain and environment.
