please tell me this problem

Mmost web sites say top leaves affected with Ca Def.but all Ive seen IME is middle leaves or older ones.Never have I seen new leaves have spots first.
You're right! Calcium def can show anywhere. Usually on middle/older leaves. Actually called semi-mobile nutrient
 
It could also be too much phosphorous. They look very similar. With the koolbloom I don't see it being low on phosphorous. Did this start after adding the koolbloom into the mix?

It did start when I first added it. I add it about week 3 after the stretch. None of my other plants show any signs. iterally just the ones directly under the light. It is a 1000w hps and they kinda close. But I know that those leaves aren't light stressed. The first pic is one on the outside of the light. second is the ones directly under

Plants that get more light generally require more feed to keep up, if something is lacking it will often show up first on a plant that gets the most light.
 
They drank a lot from last night. water went down significantly
that's a great sign. your meter is off i think.

here's what i would do (as a Maxibloom user). flush them for 24 hrs with plain water. start back on maybe 2 to 3 grams per gal of Maxibloom. that's it. no bloom booster needed.
