Yes, the white hairs on the leaves are also visible if we look closely. In our area also has land that is quite suitable for growing this plant and when there are people who use it incorrectly it is dangerous and If they use it as a medical ingredient, it's quite good. How are you friends, hope you always have a nice day.
Yep that is what I start looking for, once those hairs show up in the leaves its a sign they are starting to flower.
thanks, hope you do too.
