Browning Lawn Spots

Hey All,

Have a few browning spots on my lawn (see pics)

It wasn't mowed for around a month but has had a pretty consistent watering.

Gave it a mow and weed and feed about 2 weeks ago.

Tried a soapy water test and only a few spiders came up (in pics), do I need to treat for these?

What should my next steps be?
Water these spots everyday?
Get some chemicals to kills pests in case I missed something?
More fert?

Cheers
