if at any time anyone has any comment please speak them.
well, since you insisted in size 4 characters
I would bring the lower thick leaf plants to center front
put the tall straight stems along the entire rear
and the tall spreading stems along each side.
I would also thin/prune out the entire tank.
consider reducing the use of rock and wood,
or position them more vertically or only under
plants with thick spreading leaves in order
to increase usable rooting space for plants.
a more drastic measure is a gravel change.
those large grains are not optimized for plants.
now that you are at 3wpg, keep your lights on
for only 8hrs/day while you are using DIY Co2.
