Colloidal Silver

if you spray colloidal silver on a female plant to get feminized seeds, does it ruin the whole plant?

if you spray the whole plant and not just one branch i wouldn't smoke the bud..

can you tell me how i would spray 1 branch and not get it on the others?

You don't want to smoke anything off a plant you've sprayed with Colloidal silver. You spray them and wait for the nanners to form. Then collect the pollen from the nanners and use that pollen on a fresh female.
