CMH Blue Dream Indoor Grow - Advice/Criticism

Hi everyone,
This is a completely fictional story I made up about growing marijuana for fun. I have never grown or smoked marijuana in my life. Any pictures I post are stolen from the internet.
This is my first serious indoor grow. I'm growing feminized blue dream under a 315W CMH, 12" from the canopy. The medium is potting soil. I've been feeding with MG plant food (15-30-15 for flowering, switching to higher P/K and less N soon) and supplementing with General Organics Bio Bud bloom booster. The plant is 2' (60cm) tall at its highest and the canopy is 30"x30" (76cmx76cm). I topped and lst'd her, allowing 2.5 months for veg. I'm now on day 24 of 12/12.
I have a couple of questions:

• I've noticed that pistils developed more quickly at lower, outer meristems (shoot tips) and nodes than at the tops of colas, where growth seemed to be mainly new leaves at first and pistils emerged slowly, after a longer time. Is this normal? Does this have something to do with strain or growing technique?
• I know yield questions are usually hard to answer, but could someone give me a rough range of what to expect? I'm hoping for 2-4 oz. of dried bud.
• Can mychorrizae thrive when a water soluble plant food like MG is used? Are they beneficial when the vast majority of the plant's nutrients come from plant food dissolved in water?
• Does it hurt yields to leave tiny lower shoots that get little light intact? Should these be removed or will they simply contribute to the trim? Would they be suitable for BHO or an ethanol extract?
• I would also appreciate any advice or criticism. I understand the basics pretty thoroughly so any in-depth advice would be awesome!

Thanks for your answers/ comments/ criticism!

There are a lot of things i have to day/suggest about your grow. First that just screams at me is what "potting soil" then next is do you have other nutrients from general organics? The general organics are much better for this topic, MG is not well suited to this plant. On that same issue, if your "potting soil" is MG try something else next time. Maybe goto the store and write down the names of the soils that are in the biggest bags. These are sometimes labeled as professional mixes or nursery mixes, just let us know whats around you an someone will chime in. Expect to pay 13 bucks per 1.5cu ft bag or more. Dont pay less!

If the puctures are current make sure to cut out pretty much all nitrogen. There may be a flowering nutrient with a small ammount of nitrogen in the npk, thats ok. Dont use ANY nitrogen based nutes at this point.
If it says fox farms on it its mostly likely something you should buy if its soil, i prefer general organics nutes over fox farms but anything is better than MG almost..
Things look good overall, what week of flower are these in?

you are doing great. the plant is showing some stress, but is overall not bad. Everyone grows differently, but i think you should clean up the bottom trim. not more than 10% every few days. bear in mind that at 24 days , soon your plant is going to stop stretching and growing new leaves and start packing on size of the buds. if you can keep it healthy, you will get at least double what you are hoping for. my general philosophy is remove a few fan leaves from the top to expose more buds and remove bud sites from bottom 1/4 of plant with the overall goals of all light hitting leaves and buds while still allowing airflow so as not to promote mold. depending on RH too. dont trim too much at one time, dont want to shock it.

I have a set routine that I do on day 12 or so when I lollipop the bottom 1/3 or so. Once you start trimming and messing with larf and the crappy lower stuff you'll start lollipopping. It gets rid of the tiny stuff so the plant can focus on the buds up top.
