Plants surviving but not thriving

[Tate]

My tank has been setup for around 8 months and grew out really well at first but lately I have seen some deficiencies in some of the plants and am wondering what is going on.
Lighting is the same as when first setup and is a dual t8 run 7 hours daily.
Filtration is a Ac30 HOB with sponges as media.
I dose seachem flourish after each water change which are usually 50% biweekly.
Some diagnosis on the deficiencies will be appreciated.
FTS:

Compacta:

Baby tears:

On the compact looks like a phosphate def., on the baby tears, not sure. Are they dwarf baby tears or the normal stem baby tears? Your lighting really isn't enough for either baby tears variety though and they will struggle regardless of fertilization. To replace them dwarf sag would be a good plant for your lighting.

They are just normal stem baby tears and those are the branches off of the main plant which is in the back and cannot seem to get a picture of

Do you use root tabs? With added plant mass comes added need for nutrients. You'd be best to dose api leaf zone with the flourish every other day.. get some quality root tabs in that sand as well.

I put root tabs under crypts which are doing very well. Should I put tabs under every plant in the 6" circle it recommends?

 

[Brookster123]

Put one ever 4" and you'll be good.
