I have a plant 3' tall about 10 weeks old that has started developing 3-4 leaves with this problem. They are mature leaves not new ones. I have them growing in 3 gal.containers of miracle grow soil and using osmocote fertilizer. I have also been supplementing sea weed extract and molasses the last 2 weeks. The lights have been changed to 12/12 for the past week and I am using HPS 400 and 400 watts of supplemental flourescent grow lights in a 5'x5' room.
What could be causing this? Strange that it is only on one plant out of the whole room! Please help!

Solution to fixing a Phosphorus deficiency
Some deficiency during flowering is normal, but too much shouldn't be tolerated. Any chemical or organic fertilizers that have Phosphorus in them will fix a Phosphorus deficiency. If you have a phosphorus deficiency you should use any N-P-K ratio that is over 5.Again Peters all purpose 20-20-20 is a good mix. Miracle grow Tomato plant food, Miracle grow All purpose plant food (Only mixing at ½ strength when using chemical nutrients, or it will cause nutrient burn!) Other forms of phosphorus supplements are: Bone meal, which is gradual absorption, I suggest making it into a tea for faster use, where bone/blood meal is slow acting, but when made into a tea it works quicker! Fruit eating bat guano, which is fast absorption, Worm castings, which is gradual absorption, Fish meal, which is medium absorption, Soft Rock Phosphate, which is medium absorption, Jamaican or Indonesian Guano, which is fast absorption. Crabshell, which is slow absorption. Tiger Bloom , which is fast absorption.
