just saying hello

Firt timer, I am.  Mostly medical.  3 plants, outdoors.  A friend just drove up to our house and dropped off 3 little c-weed plants.They're looking healthy but are all different sizes.  I see buds everywhere, especially on the one.  The other two have them as well, just less.
 
Lots to learn and I have a brown thumb.  Had a million questions and answered almost all of them just by searching and reading.  Thanks for all of the information and the great site.
