dont need to see the yellow tbh ... those tips tell the story in any color . That looks like some severe nute burn ... I would flush her real good - till the runoff is mostly clear ... let her dry out some then introduce the nutes back slowly at very reduced rates . With miracle grow you can grow some good stuff but its touchy .... If you look at your bag it may be the prefertilized kind that " feeds for up to 6 month's" if so ... its very easy to burn with this kind . It doesnt release in any kind of uniformity at all ... and may release a ton of nutes at once on ya .
