I’d just flush one more time with about 10% of the flush being drainage. I’ve seen worse come back and do fine. After your flush wait until your soil is close to dry if you have a moisture meter use it their well worth the 12 bucks. And then cut back on your mute dosage a bit let them try to adjust. Hey sometimes shit happens that’s how we educate ourselves I’ve been growing for over 35 years and I occasionally need some advice as well. Especially my slowing transition from old school to newer technology.
