More pictures with better light along with your nutes/schedule would be helpful.

But to me the leaves look dark green, thick/heavy, and the fan leaves and the spot's edges have no yellowin. Looks like phosphorus deficiency. Your stems reddish in color? Whats your PH?

Manganese deficiency would be my second and less confident guess.

Suggest reading the pages for each diagnosis fully before making your decision.

You need to know your PH. Most deficiencies can be corrected by proper PH levels.
 
I am gonna buy the oh test strips so i have an idea of my ph and what should i do i guess wait a week or so i just changed resevior and uptook my nutrients 10ml eqch one but only 2 plants of the 4 have the spots other 2 are healthy

If you're PHing your water and nutes/water as well as the run-off and keeping those values between 6 and 7 you're gonna be good.
 
I heard that tap water from my state new mexico is ph perfect if i let sit for at least 24 to 48 hours... then i mix the nutrients amd leave in resevior for 6 to7 days

Run down to Home Depot and pick up a bag of this: http://www.homedepot.com/p/Espoma-6-75-lb-Garden-Lime-100508617/203192761

Mix one tablespoon in a quart of water well and water your plant with it. Then sprinkle about three tablespoons across the topsoil.

Nothing is going to "heal" the leaves that are already damaged, but your problem will not appear on any new growth from that point out. In the future, mix about 8 tablespoons of that lime in your soil mix for each grow. You'll never have that problem again, and will never need to shell out money for Cal/Mag.
 
Really? Is it epsom lime salt or what is it? And price? Im running hydro though:( does that make a difference?? And could i still ad my magnifical is remo verson of calimag but has other stuff in it i like to.. but serious props for solving my problem tacomac

Don't think lime is a solution for someone growing in Hydro....

I use advanced Nutrients because well fuck all the PH bullshit. How many people lose plants over it......... For me the extra cost is worth the insurance.
