Slow flowering or impatience

Without pics we're blind too.

 

They weren't but are now. Very stretched plants, lots of wasted space between nodes. Its pretty crowded and a very uneven canopy which leads to stretchEd plants. Have they always been under a 600? Did you veg with weaker lighting? Was the ballast set at a lower wattage? How far away is the light from your plant? If plants aren't getting the light they need they will stretch to get it.

 

I would consider that Stretched alot, not a bit. That's why the plant appears "scarce" as you put it. Do you have the option of using metal halide bulbs? Switchable Digital ballast perhaps? They'll help reduce stretch during veg and even into flower. Keeping those nodes tighter. Before I had the space I do now I really had height issues. Any stretch and I was screwed. Running mh for the first couple weeks reduced that initial stretch in flower. Stretched plants don't yeild well for their size. Bud sites aren't connected together well leaving lots of stem without bud. Some strains are stretchy but this appears more of a lighting issue. Getting your bulbs closer will help but will also reduce the lights over all usable foot print. How big of an area are you growing in? You're smaller lights may just not have been large enough to cover the area well

 

You can do whatever you want but you're not going to fix the stretching issue. What's done is done at this point. At this point I would just finish them out. The beginning flower stretch should be over or pretty much so the lower branches will never catch up. Plus it won't change the distance between nodes or "bunch" them up. It is what it is. Other then that they look relatively on par next time you want to lay a plant out flat hit me up. I Scrog. This is 1 plant and what my nets look like when I flip. It's ok for leaves to touch.
