Hello I Well love I think the first thing you have to do is to not worry about the yeild just yet and get some vegitive growth going

Personally I would not have topped those plants yet, they are not ready for it, I always top ("pinch") when there is substancial growth.

I have read you're other threads on here and I do fully understand and appreciate that this is you're first grow so it is going to be a learning experience for you

Now I don't know what lights you are using but as "Towel" says the best is MH for the vegitve growth and HPS for flowering ................... that's what I use.

Also I, don't be worried about asking questions on here about how to improve you're grow..................... there a friendly bunch ................ honest


I'll just add a pic of my last crop when they were 4 weeks old just to show you the difference between them and how the correct lighting can help



love mand xxx



Oh and keep us updated on how they are going on ................ good luck
