Hi, This is my first grow and I cant decide if its time to flower. Im growing Nirvana Northern Lights. I have 2 plants and they are about 7-8 weeks old. 1 plant at its highest point is 20.5" from the soil and the other is 19.5". They have been slow growing taller but are very bushy and were topped once also I tied back the 2 biggest branches that are not the main branches on each plant about a week ago to help inner growth. I transplanted them to 7 gallon pots 11 days ago because they were root bound in 3 gallon pots . For lights im using 23watt cfls in clamp lights and right now I have 20 cfls but once i switch to flower i have 4 more cfls in a clamp light to add to make a total of 552 watts of cfls. I have the space for them to get to be 3' max and from what i have read they should only stretch 25%-50% especially since they have been growing so short and bushy so i was going to let them go a little more so they could get bigger but now im getting worried because i have also heard they can double so im thinking i should flower now. Is it time to flower for max yield? I really would like 2 ounces a plant if thats possible. Thanks!
