Hi,
Gravel has zero nutrients for plants :icon_ques
Maybe some root tabs and or a light water column fertilization ie. a smidge of trace mineral and potassium would help, the amount of light you have plays a role in what and how much to dose.
Keep reading the forum, a little more homework on your part is needed for the plants to thrive.
