I know you say it isn't a light issue, but have you tried to raise your hood a couple of inches? It really looks like the lights are too close to me.;)

i have about 82f at the tops maybe to hot..? they still are compact at the tops and are not streching.

Yea, could be the lights too close....I keep my 400w about 12-18 inches away cuz it's not a cooltube. Tried molasses yet? or a big blooming substance? What nutes ya using? What's the resevoir temp? Ya don't want that too cold either...maybe fill out the troubleshooting form.

Be thinkin it lights too pilgrem I just went through the same thin and raised them up all be good now.

after duble checking the temps around the garden with a new teromometer its showing 4-6f more than my first reading so put that together with all the advice its probaly the heat, up with the lamps..!

thanks my fellow growers...!:thumbsup:
