is a bloom booster a good way to treat these deficiencies? and to flush can you just put your plant in the sink and give it water untill it drains clear?

It depends upon the deficiency. Bloom boosters are typically very high in Phosphorus (P) to help in the production of flowers, and also high in Potassium (K). They usually only have trace amounts of Nitrogen (N). To flush soil plants, you should use THREE times the volume of soil in water to flush. The water should also be pH adjusted, so straight from the tap is not optimal, but some do it anyways. Therefore, a plant in a 3 gallon pot should get 9 gallons of straight pH adjusted H2O (3 gallon pot X 3 = 9 gallons of water). If you are using a product to made for flushing, such as Clearex, it can reduce the amount of water needed to effectively flush the plant.

Well i treated my plants with miraclegro bloom which contains 15% nitrogen,30% phoshate, 15% potash, .02% boron, .07% copper, .15% iron,.05 Mn, .0005% Mo, and .06% zinc... it looks like one is deficient is everything and the others are starting to show deficiencies as well. shits kinda pissing me off cuz i bought these plants, i'm such an idiot

I am constantly having K, Mg, Zn problems....
These seem quite interrelated and I'm just wondering if there is some kind of common mistake associated with these deficiencies and toxicities....
I use a full Fox Farm line, from soil to flowering supplements... Should I look into some kind of micro-nute solution or something? Is this some kind of glaring problem with my tap water?

I have had this before as well. You are right, they are interrelated because if K gets to a toxic level then it prevents the plant from uptaking Mg and Zn. K can be locked out at too high of a pH or if pH has been well controlled the entire grow it may have been over-fed with K. Just remember, with fertilizer usually less is more. I always have the best results when I am skimpy with the ferts, especially since I use chemical ferts (I use some of FF line also). I am also a big proponent of regular flushing, at least once a month. This is very beneficial whether you are having signs of problems or not. It can prevent that toxic salt buildup from happening a couple weeks down the road.
EDIT: I have added pH charts to the OP showing the ranges for nutrient uptake and lockout for both soil and hydroponic.

is flushing supposed to bring down the pH? i flush with tap and the soil still sits between 6 and 7. would it be better to flush with distill water? i don't really understand if so, because the pH is pretty similar..

Flushing isn't used to adjust pH. The purpose of flushing is to remove the nutrients from the soil. There are a couple reasons why you may want to do that. Using distilled to flush may be better than using regular tap water because it would typically have a lower starting TDS than tap. Either way, you always want to pH adjust whatever water you are flushing with to the appropriate level, around 6.5 for soil.

sorry for the noob question, but what do you at to adjust the pH? would some vinegar do the trick or is it gonna be found at the grow shop?

Yes use the stuff at the grow shop if you can. Vinegar is not very effective and who knows how using vinegar may affect flavor and aroma. pH Up and Down are cheap, I buy the powder form and mix it with water and use it like that. They sell liquid form at my hydro store but it is more expensive, and is basically just the powder form diluted into water.
