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.

Toxic Salts Buildup Salt buildup, hormone problems:
Boy I am glad I found this thread! I think I finally figured out what was wrong with my plant (actually, is still, just not as bad as the photos below).
Looks like its (B) Toxic salt build-up leading to the "Intervenal chlorosis" (Say wha?) or something (*from the toxic salt build up in the photos above) that my young plant was suffering from too much salts, as the second photo says: "NOTE" says "look for white line around container". That's what I got!
And here is that browning, yellowing of the older leaves (bottom leaves). Notice its just starting, but it gets worst later.
And here's some very recent ones where you can really see the burned tips on every leaf (they are yellowing). Even the top leaves are having the problem effect them...
So, to cure my plant, do I flush it with clean water or something? I'm lost on the fixing problem thing....is it just screwed?
I wanna figure it out soon because this is the thrid set of leaves this problem is affecting, and I'm losing quite of bit of foliage....
I hope that its...

That really looks like over fert to me true herb, you shouldn't have toxic salts buildup this early in your grow

If it's just on the tips like that I'd say it's over fert, I wouldn't think you would have problems with toxic salts buildup at this early stage in your grow

OK, what's with the triple post? You're really tripping me out......and its kinda cool really...
So I should slow down on the nutrients? But how does that cause browning at the tips? And the constant yellowing on the lower leaves? Doesn't make sense...
I guess I lower the concentration on my liquid chem. ferts., that should do the trick.....
Thanks Inbred Clown dude....

Fml, my bad, I was on iPhone and it wouldn't let it go through so I kept trying till it did, others must've gone through later or something, would a mod mind cleaning them up?, nutrIent burn only affects the very tips when it's minor, probably because it's the thinnest part of plant innit sure exactly why though, I generally don't worry bout leaf yellowing etc when my plants are seedlings unless it's affecting the top 5 cm of growth I find the lower leaves often yellow and die, though I am unsure how sever it is on yours, but yeah I wouldn't worry too much bout the over feet it's very minor if that's what it turns out to be
Blessings
