Looks like moisture retention or possible transplant shock. Make sure the soil is near-dry before watering or feeding. Cannabis prefers a wet-dry cycle. When was their last transplant?

Full-strength CalMag is unnecessary during the growth stage, and it will cause problems when overused.

Did you top her already, or is that just how it's growing? What are the overnight (low) temps?
I am pretty sure not an over water , I did that last grow and did let dry before water- I did transplant 8 days ago though. I was told by Botanicare rep to use cal mag every water and feed with RO water - I am only using a small portion of recomendation - I have not topped , natural growth pattern there - night temps are 75 to 76 currently and have been since start thanks for your help again
