Is this due to mower blade being dull?

Dull blades will make the tips white

Looks like two different kinds of grass. Where are and what grass do you have? Did you overawed lawn?

Do you mean did I overwater? I don't believe I did. I tested with a screwdriver and it doesn't appear to be overwatered, but I could be wrong.

I water 3 times a week for 20 min each time.

Also unfortunately I don't know what type of grass it is, I've tried looking it up, I think it might be Zoysia based on pictures I see online?

@Jfong5 I think the typo was asking if you overseeded. It just looks like dull blades to me but you will want to do an irrigation audit the find out how much water is going down in your 20 minute sessions. LCN did a video a while back explaining the process: How To Set Irrigation Zones for Watering The Lawn.

Thank you I'll look into doing an irrigation audit as well.

A third vote for dull blades. My front lawn started getting white tips earlier this spring before sharpening

I meant overseed. Do you have cool season grass that is starting to die off

It is possible it is Kentucky bluegrass, it is either that or Zoysia based on pictures I see online.

Even with a sharp blade, rotary cut zoysia will have split blades and some ragged tips, but not quite as bad as in your pictures. Keep your blades sharp. Zoysia in particular dulls blades quickly largely due to a high silica content in the grass blades, at least what I have been told. Regardless of your turf type, like the others have said, your blade(s) are dull.

Pull a sample of your grass and post a close-up picture. You (and we ) need to know your turf type.

We do! It’s got great potential.
