Ok, so I have heard that is possible for a plant to go hermi in the middle of a grow cycle and become male. Is it possible to notice/prevent/stop/reverse the hermaphrodite tendencies?

Nope once its hermi its hermie.Some will say cut the male balls off but you still have a hermie plant with low thc and hermie tendencies

if it's a late developing hermi with only one or two male pollen sites you can get sensa-spray or dutchmaster reverse and penetrator (you need both) and it will stop them from coming back. You can even use it to prevent hermies from the start, great stuff.

what kind of cost am i looking at for that stuff? If its just one plant that i'm gonna lose it may not be totally worth it. Is it worth it to save the plant. Its a no name strain, a seed from one of my ounces.
