you shouldn't need to top it till its 18 inches and it should have shoots unless its not growing shoots than top it at a foot tall
its a bushy mofo and it should be a quick finisher

get a 250 switchable hood with a built in ballast you can get the 400 for the same price i sun burst sells them i think there like 190 for the whole package
if it shows no sigh in a week its prob something else get some vermi t it will help the plant uptake what it needs not what you feed it for the most part or any bugs hook your plants up
8 in pots in a 4x4 hightide grow tray with white Russian it will need to be a auto or a short strain for a scog just fill the entier tray with clay pebbles that way your roots can go where they want
