Incredible slow growth and leaves are turning neon...

It's a lockout already, if you don't want waste time , star again, you will loose maybe one week at the end, a bit of soil and nutes, plus electricity bill, BUT You can stop feeding her for 3 full waterings, dry out, water, dry out, water again and etc Lift your pots, it's easy to feel, they have to be light, you have to follow this, because otherwise pH imbalances and all the rest .... Follow strick PH, don't play here. Root Juice for first two weeks max, your plants older. Fish mix is insane strong, can cause toxicity, I had amazing results with it, but few huge mistakes too, out of my use, all other range is more than enough in soil. She should bounce back, old leaves will never tho ... With time if plant goes big and bushy you anyways would take them away. All the Best !
