Hm... My plants are kinda parallel to yours, except I am a lazy grower... I bought cheap soil, cheap fert (mixed into the soil before planting), and used water straight from the tap... my plants are about the same age as yours... vegged for 6 weeks, now at week 4 of flower... I topped and mildly LSTd mine.. so none of my stems/branches look nearly as long, and there's a lot more bud sites... but what I notice most (aside from the quantity and size of the buds... which yeah I seem to have more and bigger) is that mine have a lot more leaves. A few even still have the first fan leaves they grew (which are relative huge now, and mostly dying). I've really hardly lost any leaves, over all (maybe 10-15%).
I did a lazy veg... just put the plants in the corner under some home cfl lights, and not nearly enough of them... 480wats max total... temps were mostly low 50's-mid 60's.
