Sounds like a fertilizer issue to me.
I think it's higher nitrogen count that promotes leaf growth?

Looked it up:

"Nitrogen regulates the growth of stems and leafy green foliage.
Feeding your plants with a fertilizer high in nitrogen promotes
rapid growth in leaves and stems. The plants that benefit the
most from nitrogen are grasses, herbs and leafy vegetables."
