I only started to like vegetables when i was an adult
When i was a child i didn't like vegetables, but started to like them as i got older
If you didn't like something all the time then you would say 'started to like'
'When i was a child i didn't like vegetables, but started to like them as i got older' this explains when you started to like them
何かがそれまでずっと好きでなかったなら、それは 'started to like'（好きになった）で表せます。
'When I was a child I didn't like vegetables, but started to like them as I got older'（子どもの頃は野菜が好きではなかったですが、年を取るにつれ好きになりました）
この文は、それをいつから好きになったのか伝えています。
When I was a child, I did not like vegetables but only started liking them as I grew older
When you want to explain that you did not like vegetables as a child but came to like them as an adult, then you can say it in the following ways:
-When I was a child, I did not like vegetables but only started liking them as I grew older
-I only started liking vegetables as an adult.
-I hated vegetables as a child but now (as an adult) I love them.
子供のころは野菜が嫌いだったけど大人になって好きになった、と言いたいときに使える表現です。
-When I was a child, I did not like vegetables but only started liking them as I grew older
子供のころは野菜が好きじゃなかったけど、大人になるにつれて好きになった。
-I only started liking vegetables as an adult.
大人になるにつれて野菜が好きになった。
-I hated vegetables as a child but now (as an adult) I love them.
子供のころは野菜が大嫌いだったけど、（大人になった）今は大好き。
When I was a child I disliked vegetables, but now I like them.
You are an adult now, so you will generally use the present tense and the word 'now', as shown above. This shows that you currently like vegetables but there was a time when you did not like them. You can also specifically say that when you were a child you didn't like them. You could also use the phrase 'as a child...'
You may not like all vegetables now, so you could be specific and say 'I never used to like cabbage, but I like it now', or 'when I was younger I didn't like cauliflower, but I like it now'.
今はもう大人になっているので、普通は上記の通り現在時制と 'now' を使います。これで、今は野菜が好きだけど昔嫌いなことがあったと表せます。
また、具体的に 'when I was a child'（子どもの頃）と言うこともできます。'as a child...'（同）を使ってもいいです。
今現在全ての野菜が好きというわけではないかもしれません。その場合は次のように具体的に言えます。
'I never used to like cabbage, but I like it now'（昔はキャベツが嫌いでしたが、今は好きです）
'When I was younger I didn't like cauliflower, but I like it now'（若い頃はカリフラワーが嫌いでしたが今は好きです）
I enjoy vegetables now but I didn't when I was a child.
"I only liked vegetables once I grew up." This explains to the person that now that you are an adult you like vegetables but you didn't when you were a small child.
Eg: Have you always liked vegetables?- "No, I only liked vegetables once I grew up."
"I enjoy vegetables now but I didn't when I was a child." This is another way of explaining that you like vegetables now that you are an adult but when you were a child you did not.
Eg Did you like vegetables when you were a child? - "No, I enjoy vegetables now but I didn't when I was a child."

When I was a kid I hated vegetables, but now I love them!
When you are talking to someone you don't have to tell someone you're an adult if you are face to face with them. You can of course replace the word 'hated' with the word 'dislikes' and the word 'love' for the word 'like'. It all depends on how much or little you liked vegetables.
I went from disliking veg as a child, to loving it as an adult
