Should i just give it molasses or mix the two? If not i have miracle grow bloom booster as a last resort. IM 4-5 weeks since switch to 12 12 so i figure 4-5 to go. I also flushed it with straight water the last 3 waterings and have noticed a lot of the bottom leave yellowing at once. I know their supposed to yellow during flower but would a lot changing at once mean it is sucking sugars from leaves? Would molasses help for this? Sorry this post kinda went all over the place, but still thanks for any advice.
Molasses is simply a supplement to provide trace minerals, and the sugars also help supplement the micro-biological activity in the soil. It is a good supplement to give several times during a grow, but in no way would this be considered a substitute for a proper fertilizing regime.
I give Molasses at two points in my garden... once at mid veg when they really need the micronutrients and then again during the last 2 weeks of flower when the buds are packing on their final weight.
The yellowing you are seeing near the bottom at mid flower is normal as the plant shuts down its big production plants low down on the plant in order to concentrate on the buds. Pictures would help to be sure about this, but this sounds normal and nothing to be alarmed about.
