Twice a week maybe too often, or too much for nutrients, if it's growing in the ground.
When has it been getting plain water?
What are your nights like, are they generally on the cooler side?
My own climate is warm or hot during the day, but often cold during the night.
It's not uncommon for me to see yellow tops in the morning, but clears up later in the day.
Especially if it's just rained, or soils been watered the day before.
When you planted did you amend the soil some?
Dolomite lime, organic matter, aeration / drainage?
I don't think there's much wrong at all myself.
I'd be careful I wasn't overdoing the fertilizer, because there's no flushing it out if you do.
Watch you're not watering too often and leaving the soil beneath soggy all the time.
Outdoors, in the ground, I'm a big believer of soil fertility being more necessary and more effective at resolving problems, or keeping plants healthy, than nutrients.
It's a decent sized plant and looks to have been planted where it is for a little while.
So if you're quite certain you aren't over doing the nutrient and nights have been on the cooler side, I'd suggest adding some fertility to that bed.
Some cow manure spread around, dust the top with dolomite lime, add an inch or two of light mulch or straw.
That's how I'd go about it myself. Looks like just what it needs to me.
Give it a couple weeks to break down some, only giving it plain water.
Then you can absolutely continue supplementing them the nutrient you've been giving, when you reckon they need it.
That's my 2cents mate.
Hope it's of some help. Plant honestly looks pretty fine.
