Help with Stauro plant deficiency

Just wondering if anyone could identify what is going on with my staurogyne repens. Tank is a lower tech 40 breeder with 2217 filter, 2 36-inch t5ho Sunblasters and is stocked with Blyxa japonica, Hygro compact and the staurogyne. The tank has been flooded for two months now and everything else seems to be doing well. Here's what I've been adding to the tank:


1/4 tsp kno3


1/8 kh2po4


1/16 csm+b


1/2 tsp equilibrium


This is added weekly


1 capful of flourish excel daily (2 at water changes)


Any help would be greatly appreciated!


Thanks

 

Thanks Solcielo!


So add more kno3?


Should I does more frequently?


This is


My first lower tech set-up so I'm struggling to find a proper regimen.


Thanks

 

The lights are suspended prolly six inches above the tank and I can adjust them higher pretty easy. Haven't had any algae issues just the problem with the repens. I'll try doubling the potassium and see if there's any improvements.


Should I raise the light even higher than 6 inches above?

 

Unfortunately I have no par meter...I'll raise them up a few more inches.

 

There are snails in my tank for sure. All over in fact and yes they do get on the staurogyne. There is no possible way I could eradicate the snails at this point. To many snails and too many plants. I wasn't aware that the snails would do damage since they never did in my other tanks.


Any suggestions to help curb the snail problem?
