Thank you for contacting eXtension. What is your geographic location?

Hi! Thank you for responding, I’m in Fujian, China.

Two things: 1) Leaf-miner - an insect larvae that feeds below the upper skin (epidermis) and the lower epidermis. There is no control for leaf-miner in vegetables once the enter between the layers. Most all plant will grow out of this problem. See:
leafminer larve damage

2) Your plants would benefit a bit from a very light application of nitrogen. You can use Miracle Gro, Rapid Grow, Peter's Soluble Fertilizer or simply 21-0-0 - once every two weeks if your school project allows.
