you're really going to need some more light. it looks pretty good so far, but you won't get much yield with a 75 watt led (which is probably more like 25 watts in reality)...the led bulbs with plastic tops are a fairly economical option, with a few clamp on holders. pry the plastic domes off and get the lights as close to the plant as you can. cfls are also an option, but they use more power, and produce more heat. t5 florescent lighting would work as well. pretty much anything to get more light will help more than anything else at this point. a little molasses wont hurt, but don't rely on it as food for the plant, it isn't, its more to feed organisms in the soil, and you don't need very much at all to do that.
a good quality fertilizer with a low first number, medium second number, and high last number is what you want for flower.
i use Jack's 5-11-26 with a little calcium nitrate (the jack's has NO calcium, it interferes with sulphur uptake.) just add a little cal-nit first, let it disolve, then add your nutes. use about 15% of your total ppm as cal-nit, and the other 85% w/e nutes you decide to use.
some come with calcium, but the ones i've tried haven't been as effective as using the two part formula. i still seem to get mag problems about halfway through flower with them, not so much with the Jack's-cal-nit.
