mix it at 1/4 next time a little more. then watch and adjust as needed. I don't know anything about your nutes so can't say for sure but 1/4 mix is usually a safe way to start new nutes. Mine is a 0-10-10. and don't have any problems at the full mix. You could also add blackstrap molasses and super thrive if you wanted. thats what I use most of the time.
