Yellowing among all my plants...

Having some plant problems, hoping you guys could get me on the right track.. Thought it was phosphorus deficiency. My regular schedule is every other watering with botanicares full lineup, but once I noticed this I started to up my bloom formula and start fertilizing every watering, think I might have over fertilized one plant.

Well she's not doing the claw nor, are your tips white. Doesn't look too burned to me. If anything as pale as those leaves are i'd think about feeding a dose of N with your bloom nutes next time. I also wouldn't feed every time. Feed, water, feed, water.

Currently I'm giving them 5 ml of both bloom and veg, I've been adding a little bit extra bloom. And I only started feeding every watering when these symptoms showed up, went easy on it too. I guess that's what I should have said.

If you just made the switch to 12/12 i'd give more grow nutes then bloom nutes or at least even amounts until the stretch is over. Plenty of time for bloom nutes get her nice and green quick. So you'll get a decent yield. Just my 2 cents. Do you use cal-mag?

Flush to get rid of excess nutrients and salts, then start back on a lower nutrient concentration.

Will do, I only mentioned overferting that one plant so you guys wouldn't give me hell on the down curve of it's leaves haha. Only seems to be that one plant showing symptoms of excess nutes, the rest are yellowing differently so I think the rest have the opposite problem...

Okay, the plant made it obvious today. I'm pretty sure I've figured out it's potassium, as you can see from pics it's very clear the yellowing is going tip inward, and all the veins are deep green though not easily visible in picture. My tops are still green, so tells me no sulfur def. I've already told you guys I've been giving it flower nutes so with all of your help I've come to the conclusion that my ppms must be high and locking out potassium. I've got five gallon pots, how much water per plant?

Tell me what you guys think, I think I've got it nailed down but double check me anyway:

yea it could be potassium but i dont see rusty spots of the leaves which it would cause. i would check your ph make sure its on track.

no matter what it is just try giving it clean ph balanced water to leech out any excess salts. after this give it veg feed of some sort. I use dyna gro it has all the essentials in it already. Maybe your using a soil that has time release fertilizers and when you water it with your nute water its doing a double dose? thus creating a lockout

Flushed five gallons through, ppms are 750 and the ph is ever so slightly past 7. A little low to be lockout, isn't it?

dyna gro is some amazing nutes you will never have a def unless your ph is off. And no not really slightly over 7 is not to low to caus a lockout, 7.0 can cause some problems after while.

Since I've flushed my pots both with 5 gallons of 6.5ph water, and in addition giving them a fresh round of grow nutes with a little ph down to counter the nutrient's alkalinity, I've done everything I need to do right? Just wait?

Thanks guys for all of your help!
