i have used pk 13/14 before but have recently been told by a friend that i can use it for a longer period of time than the bottle suggests, the bottle tells me to use it once 3 weeks before harvesting for 3-6 days if i use it for a longer period of time will it harm my plants as i thought it was only contained phosphorus and potassium which i thought the plants want most during flowering and would only benefit them ????
