Looks like you got a good grow going...
Vegged my NL for 5 weeks - unfortunately only 1 was female!
I didn't trim or top it... now it is too big for the grow room!
I've had to stake it, lean it over & turn daily... Switched to 12/12 1st Nov so that makes 8 weeks now? Bout 100cm tall. Still prob 2 weeks to go.
Getting impatient and tried a few buds... already an ok smoke!
Not sure which plant ended up being the female... I think it was number 3 (LHS pic1) ... They wern't as yellow as they look in the pic!
