Well I have found an additive that will stop the stretch in other species I have. I use it to control the height on some of my stretchier sativias. Just one dose will stop it. Called Phosphoload. VERY spendy stuff, like $100 per liter. Also is not 'organic' and because of that I do not recommend this even though I use it.

Just another tool in the tool box of cannabis growing.
