Question?

[smoken Sexy]

I have 3 beautiful 1st time plants..They are getting huge..But no signs of flowers or buds? Its been around 4 months (maybe a little more), I follow all the instructions , water on time, perfect lighting fertilizing ect?

How long can it take for Hydro grown plants to start to get their male and female flowers?????? Just starting to worry here...
Thanks for any help..
