So I have this Huge GG4 plant from which i sprouted from an immature (light tan colored) seed i found in a dispensary nug. Well it was a strain that smoked really good and now I have this huge bushy plant that is just not looking as lively and perky as she once did...ive never cut any clones as of her yet...still kinda learning how...but all its been gettin recently is PH water. What are some good mother plant nutes out there? And whats the best way to keep this mother looking her best?
