Deficiency

I am growing in ProMix and I'm not sure how to fix this problem. Any help??? I'm never sure when it comes to this kind of medium. Its not soil and its not hydroponic and that's where most of the information is.

How far along is your plant? Could you repot into some cannabis specific "soil" mixes?

What's the pH? I read on the website that they recommend a pH of 5.5-6.5 with Pro-Mix. What nutrients have you been using? If possible, it can also help to post a picture of the plant in the setup
