L.E.D. Lights, Nutrient Deficiency, or Impatience?

I've been working on a nice little closet set-up with some seeds (possibly Afghani Gold). The original buds were massive and juicy with an average of 7 grams a bud. I am in the 4th week of flowering and research indicates that the plant is supposed to yield 300g/m^2...the leaves are crystalizing nice, but the buds are small with a lot of internodal spacing between them. I am using eco-friendly lights which consist of 5 EcoStar Grow Bars (ecogrowbar.com) arranged about 1.5 feet above the plants and two on the sides. The lights are supplemented by four 150Watt equivalent fluorescent swirl bulbs with a 4 ft. fluorescent ballast with 65K color temperature...also I am using Miricle Grow Bloom Solution 10-30-10 for the budding stage...am i making a lot of mistakes? Here's what the closet looks like... PEACE!

Hey, from what I can gather, it sounds like your LED's are too far away.
Also, the listed yeild you are referring to is under ideal conditions. I dont think the seed bank took LED's into consideration when they wrote that. Not saying you wont get a good yeild, just saying that in order to get it, everything has to be perfect. Most people do not get the advertised yeilds though.
Peace

push those led's to like a quarter inch from those babes

I agree with video sounds like the lights are too far away. Do you ph test? What is the temp of your grow area? Next grow I would try Fox Farm ferts.
