Hi Binz,

they look pretty, apart from some yellowing of lower leaves.
As stated in the chat, I'd give them some side lighting and remove the big side fl you currently have as the plants will grow nowhere near that big.

Adding another fl on the back and on each side at plants level would sure help a bit.

Keep up the good work! :thumbsup:
