im using canna nutes flora right now and im about to start my fourth week of flower. i wanted to add pk 13/14 to my res but my question is, can i water my plants with that same res for two weeks?

it says only use pk for one week, but if i use it for 2 will that be bad? or will it make my bud grow more..
