I agree with @Borderryan22,check your ph and test the ppm of what your feeding and the ppm of your runoff. Assuming your growing in a soiless medium.

All over the plant, predominantly at the top though.

@Tonysmom maybe its what @Borderryan22 stated but for me its hard to see

I like to retract my last statement i believe its a manganese def not a phosphorus def as phosphorus deficiency is a rare occurrence in cannabis plants and manganese def looks very similar to phosphorus def and get mixed up quite regularly

Thank you for the response. I am going to adjust the pH which hopefully will help the plant absorb the nutrients in the soil. All of the best to you.
