I'd say magnesium. Folar feed with epsom salt. 1 tsp/quart. Keep plant out of strong light until droplets dry.

Also looks a little like N def. I'd be concerned about your soil ph. Measure runoff ph (try to consider how long the water sits in the soil until it is displaced into runoff).

Do you let the soil dry between waterings? Container should feel very light when it's ready to watering, just before leaves start to droop from being too dry. If you're overwatering it will hold the soil ph lower, not letting the roots experience higher ph as the soil dries.

cal/ mag in the diet wouldn't hurt. I see a little deficiency but not life threatening. What kind of light are you running? I almost want to say a little more N but your tops say your good.

Yea I let it dry good I never overwater, but I found the problem! the thing is that I use water from the water we drink in the house, and it water purified with reverse osmosis so now I feed 15 drops of 7-7-7 of violet purple in a liter of water. one week regular water and 1 week with nuts. and it doesn't have Mg in it xD thats why 1 month ago I had the same problem but worst because I started to have a lot of deficiencies and my guess that it was a PH problem but testing the dirt it was almost ok so later I discovered that I was using reverse osmosis water xP

RO water is good, usually better than tap water because no chlorine. You should buy a calmag product like Botanicare's CalMag+. Use 2ml/gal to replace the minerals lost from RO filtering. You may have to increase it to 5ml/gal in flowering.
