Looks like slight lockout from too much N - I would do a flush, let it dry, continue to water only for a week and hope it stabilises and no further damage appears, then continue feeding. I see you also have a RQS diary where you have early toxicity signs (that tip decoloration), 3ml/l of terrabloom in 2nd week of flower on autos is quite a lot, you probably would be better off using only half of that.
