Advice needed please

I’m growing a photoperiod feminized Agent Orange. I was trying hydroponics using coco with a top feed ebb and flow system. The top bucket was 3.5 gallon and the bottom was a 5 gallon. I started getting a sulfur smell only when I fed. I have since pulled it from the 5 gallons and put a fabric pot around the bucket. I’ve cleaned the coco with diluted peroxide and the smell is gone. I plan to feed it by hand now. I’m in week 4 of flower and wonder if I should continue growing or just cut my losses? The picture is from the other day and has since been cleaned. It’s lights off now but can update the pic tomorrow. Some positive advice would be great but I’m realistic. Thanks in advance!!
