Plants Are Happy But Something Is Wrong With Them

[Mikaila31]

My Hygrophila polysperma is very happy and the last couple of days it's even been pearling , But there leaves have also started disinagrating from the tips or the edges . All the other plants are fine even the big leaf variety that i have. It's in a 20gal. with 2 wpg. and a flourite substrate, no fish yet, and a dose flourish once a week. So what's wrong with them and how do i fix it?

Some plants are known to be sensitive to flourish (or flourish excel ) and 'melt' away. Not too sure.

Youve got lots of light on the tank... are you adding co2 at all? You also may not ber fertalizing enough. Maybe try adding the flourish twice a week for a while and see if anything changes
