    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.

    I agree, it looks like either a calcium or manganese deficiency.

    You need to know your PH. Most deficiencies can be corrected by proper PH levels.

    Feeding with the proper pH is imperative for good nutrient uptake.

    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.

    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.

    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.
