Your problem is that the inter-nodal distances are too great. Means the branches are too far apart and that cuts down on the number of budding sites.
If you plan on keeping her vegging another 10 days or so I would top her today. Cut off the top 6-8 inches and use that top as a clone. Topping during veg tells the plant to grow more secondary branches, which is what you need.
Good luck, BigSteve.
