There prob is a pH prob going on.
But if not...
Do the plants look like this?
i would also consider the 1000 watt mh only 14 inches above the plants. I do know my mh burns hotter the my hps. Check the temps at your plant tops. Would check the simple things before i would go adding anything to correct problem. Also noticed no exhaust fan. I am leaning on heat stress. Have a pic?:thumbsup:
I use 1000 wats have been for 2 years i suggest you give 18 inches i never put less than that and check the temp at the top should be around 25celsius and if you could put some pix itl be easier to figure out the exact problem hope they get better
