Good morning, dear friend @anggreklestari.
I'm sorry it's so hot there and that it's affecting your plants; but, as you say, it's all part of the learning process.
The cabbage plants look great; I hope you're enjoying them in your meals.
It's wonderful that you've chosen companion plants to protect your vegetables from insects.
You have a great variety of plants, they all look fantastic.
I wish you much success in your garden.
Have a beautiful Sunday.
The process is learning 😊 thank you my friend
