What are your temps in your room? You only want your room to drop 10-12 degrees when ur light are off. My room is 85 degrees lights on and 75 degrees lights out. When your temps drop more than 15 degrees it will cause your plants to stretch. Call your local grow store about a new product called Dr. Nodes. It will stop your plants from growing any taller. 250 ml of Dr. Nodes into 50 gal of nutrient. You only have to do this once. Good luck i hope this helps.
