Have loads of problems with my plant.. It's 20 days into flowering , and before I had som yellowing of the leaves , thought it was nute deficiency and magnesium deficiency . So gave nutes every feeding as supposed to and gave it some magnesium. Now it looks like i've got nuteburn and leaves are still yellowing aswell. Could this be a ph problem ? And also. It turned out to be a hermie, and it pollinated itself, is it worth saving ? Will there still be any smokeable bud ?
