there is nothing wrong with the nutes you are using infact it is probably one of the most commonly used brands for growing cannabis.
would suggest you get a ph meter and ppm meter to be able to better check your nutrient strength and ph.
is just one plant showing this problem?
would probably try increasing the strength of nutrients slowly to see how the plant reacts as it could be a nitrogen deficiency.
