I know this has to have been posted before but I searched and couldn't find it. My plants are three weeks old on Monday. Im sure they still have a ways to go but how will I know when to start the flowering? also, there's two of them, and one has these sort of green pistil looking things coming out of the very top in between all the leaves, like in the center of the plant if you were looking down on it. like this sort of <*> with <> being leaves and * being the "pistils". I'm sure it's normal....but is it?
yes, that's normal. it's just a growth tip. 6-8 weeks veg, or whenever you feel the need to, depending on how big you want your plants.
