Please help with leaves problem any ideas????

Hi guys I have strawberry kush about 6 weeks into veg I have leaves around the plant doing this maybe 2 a day the rest look fine but hoping I don't have a problem any advice would be great thanks in advance

remove this old tired leaf, pay attention to new growth, your plants look great.
when do you plan to flower?

There is approximately 2 leaves a day I am removing I'm lookin at switching pretty soon due to height issues I'm currently sitting at 45cm high
