I recently set up a new Fluval Roma 125. Its been running for a month now and all has been well until recently. Its a double island type set up with both islands raised and the substrate is fluorite black. with aquarium sand along the front and in between the islands. I have red moor roots with Anubias nana and Bonsai, java fern and Java moss attached. These are all growing well.
Planted in the fluorite I have Bacopa Caroliniana, Staurogyne Repens, Echinodorus and straight Vallis. I have been using Seachem flourish once a week. The Bacopa and Repens wee growing fine, with some Bacopa reaching the surface.
My problem is the Bacopa leaves now seem to be melting and the Repens is slowly starting to turn yellow.
The lighting is standard for the tank two 15 watt t8 tubes. One aqua glow, one power glow. I was told to only have the lights on for 6 hours for the first month as it is a new set up. Should I step it up to 8 or 10? I am not using co2.
What could be causing the demise of the Bacopa and Repens?

You do not have complete ferts. It may no be the complete answer either, but won't
hurt to remove that as the cause by starting them.
Do not just run out and buy the first thing that comes to your mind. After reading the link, ask more questions on here as there are many options.
The shortest distance between any two points is a straight line...in the opposite direction...
Thanks for replying guys, I'll try to get some pics up soon. The leaves don't have holes in them there going yellow from the tips of the leaves inwards, the very top few leaves are ok it seems to start about 3 leaves down.
The plan was a low maintenance set up so I don't really want to go down the co2 route.
Which "Flourish" are you using? I know Seachem's labelling on the bottles is really misleading, but "Flourish" is actually the name they use for their entire line of fertilizers. There's Flourish Excel, Flourish Comprehensive, Iron, Nitrogen, Potassium, Phosphorus, etc etc etc. You actually need to buy quite a few different "Flourish" bottles in order to provide a balanced fert regimen for plants.
Flourish Comprehensive's label unfortunately is quite misleading. Comprehensive is mostly just micro and trace nutrients- actually, those nutrients that plants need in LEAST amounts, compared to carbon, nitrogen, phosphorus, and potassium.
If you want to stick with Seachem's line of ferts, you will need to pick up quite a few more bottles. Their "Enhancer pack" is the macro nutrients that plants need in the greatest amounts. Seachem has a recommended dosing chart on their website.
