Weed/colas

Are these colas super stretched or will this eventually turn into 1 big cola/bud? They are 20 days into flower right now, I'm growing indoor using 1000 watt HPS light.

It's normal. They look great. Keep doing what you are doing and they will fill in later. It's early bloom stage.

1000w bulbs grow big buds!

They stretch in the start then they start filling up and filling out as they mature as long as you treat the right and give them good light. You have a 1000W hps so that is good light, as long as it's not too far and not too close.
