Yeah man,that looks to me like it lacking a in a few areas along with a slight PH issue and possibly an abundance of foods that aint moving too n building up your issue slowly.See I dont see overfeeding,but Ive yet to have that issue yet.Ive had a HEAVYYY flash feeder with WAY too much N for my liking and it looked nothing like that,so thats why i dont see a too much N issue.well assuming your soil is farily ballanced and I dont believe it is,hence the discoloration.imho I would build a repair tea thats stupid mellow but several lighter additives that'll help balance that out.but thats my take on it bro.
