was only like two and a half weeks !! y what could happen
I think NOWitall is referring to the potential to genetically "morph" your plant. Meaning hermaphrodite.
Screwing with light cycles always has the
potential to cause genetic anomolies.
That being said, I have cropped plants that have gone full cycle, left nugget buds, some stalk and leaves, then reverted the plant to a 24 hour veg cycle. After a few weeks or so, I had a new veg mother for clones, and none of the babies from that mom showed any signs of hermie throughout their life cycle.
I did this because I started with bagseed, and had a shitload of variety in my room. All the plants kicked ass, some more than others, but most had desired traits. ONE, however, was the best strain I ever grew. Not for yield, or size, but just sheer "couch-lock" stone and crystal count. I decided, after reading about it, that you can bring a plant "full circle" and make it a mom for clones. Just remember though, this CAN cause problems, as in effect you are bringing something practically dead back to life doing this.
You ever watch Pet Cemetary????? LOL.
I think you would be alright at 2 wks though, as flowering would just be starting and you didn't take the plant thru a full cycle. Just keep an eye out for little nutsacks or "bananas" interspersed in the buds. These can ruin a whole crop super quick.
