Here's the pictures..

I was thinking it may become short if I scalp the lawn and restart frequent mowing (every other day). But looks like bermuda may not look green all time, unless its overgrown I guess.. By the way, thanks @User.

Liked the color but not the weed!
Recent pictures prior to mowing..

After mow

Once in a month.. 23% nitro, 1200sqft in size. I still have thin spots everywhere under the full sun. Will aerate help?

I wished but unavailable at any stores in my country. If so, may I know your recommendation if term of N-P-K rate other than a specific product? Regardless, my soil test is still pending...

I will review the Scott's Max soon. I did apply Scotts Weed and Feed before for the last 4 months. Was just okay, less green effect.

Noted on the aeration point. Thanks @User

No wonder, in my country, temperature above 83 degrees is a common thing throughout the year.. (tropical)

Local Temperature

Someimes rains everyday.. That the issue I guess. By the way, recently, to experiment, I did scalp 2 portion of my lawn. 22mm and 32mm.. Its been a month. Here is current photos..

Vast difference after scalping..

Another view..

Looking forward to future pictures.
