[TD="width: 85%"]The colloidal silver simply combines with the copper molecules in the cannabis plant. It doesn't change the plant physically or genetically - it is the same plant ... however ... in female cannabis plants, copper is used for ethylene production which lets the plant know it is supposed to be female and produce female flowers. When the copper molecules are no longer freely available in the plant (they are bound to the silver molecules that were in the colloidal silver) the plant no longer produces ethylene (where the CS has been applied) and no longer will grow female flowers (where CS has been applied).
The plant will produce flowers when sexually mature and put under the required 12/12 photoperiod lighting schedule, but if the ethylene is not present at the bud-site then the flowers cannot be female, and the plant is forced to grow male flowers.
If you apply CS to a part of a female plant, then that part will not be able to produce female flowers and will produce male flowers ... JUST where the CS was applied.
It is not stressing the plant.
Plants operate through a number of different chemical indicators and hormones - what they do is dependent on the presence/absence of these hormones/chemicals. They don't have eyes, ears, fingers etc. as a means of assessing their environment, nor a brain to process whatever input they get. Their whole behaviour is controlled at a chemical/hormonal level, and by manipulating these indicators we can control the plant in some areas.
There is too much emphasis put on "STRESS" causing hermies.
Cook them, burn them, snap them, starve them, poison them, do whatever you want to the plant and it won't hermie ... unless you significantly screw with the lighting schedule. Repeatedly interrupt the dark period (when flowering) with bright light and you will probably turn the plant hermie (if it is susceptable to such stress). Pretty much anything else won't bother the plant.
Colloidal Silver does not STRESS the plant, and as just mentioned STRESS is bullshit, light poisoning is the only stress that causes hermies ... except extreme old age when the self preservation trait kicks in.
