How is my plant looking?

Hey guys just looking for some opinion on how this plant is looking?
This is my 2nd grow and by far the best one. I had a few problems early on with my light falling but fixed that problem real quick. But any opinions are appreciated happy growing.Also one question, considering my grow space would i be okay to go ahead and do 12/12 cause right now im doing 20/4 at the moment.
Here are the pics

Some will say go to 18/6 for a couple days and then 12/12, looks good.

ill sure do that and ill keep posting more pics once there a few more weeks older
Right now ill switch to 18/6 for about 4 days then ill start my 12/12 thx for quick reply
