Hi

I have celebration bermuda lawn. I am currently cutting at 1.4" with a sunjoe electric reel mower. I did a big dethatch and scalp 4 weeks ago which really browned the lawn. It has come back nicely - however I have these annoying white tips that will not go away. Are these stolens? they have little green grass blades attached but 90% of the blade is white. I have been mowing like this for the past 4 weeks and am not seeing improvement? any advice?

Thanks

Phil
