Can i top this plants they was leggy last weeks D...

Hi @MR_Greeen! On the one hand, it is the perfect moment to start working on the mainlining approach. On the other hand, building such a manifold requires a strong plant with a nice apical development. A slow-growing plant will be very hard to manage on the long term, you better select the strongest phenotypes to proceed to mainlining, or you will need to be patient! Hope this will help, I'm also a big fan of this technique so please have a look at my diaries for some training/mainlining tips and feedbacks. Happy growing! 👊
