Yes, get rid of ALL those damaged fan leaves. Your plant will thank you for it!! Many of those leaves have absorbed way to much fert, and are harboring it and aren't serving any more purpose. Go easy on the watering, too. Your flush did it's job, but too much water isn't what this plant needs right now. It needs time to recover. Remove the fan leaves, maybe a little more duration on the light (to slow the need to bud), cultivate the soil on the top of the container to aeriate it, and have patience. With a little R&R your plant will recover, but will be just a little behind schedule.
