Piri piri chili plant problem

Hi! I had bought a Click and Grow for my home, the plants have been growing at a slow speed but what is bothering me the most is that they have started getting ants, white powdery substance on them. I had bought three peri peri chillies along with it.
Please help.
Here are the pictures of the plant -
