I did<g>, 1st dose was a tablespoon of honey in 4 cups warm water, stir good to blend, then gave plants 2 cups each. Plants were started from seed on 5-8-11, switched to 13d/11n on 6-08-11 for 2 weeks and then to 12/12 on 6-22-11. Today have dime sized buds all over the place.
I'm considering adding 1/2 teaspoon per gallon every time I give it nutrients and plain water up to the actually day of harvest.
These plants suck up some nutrients.
