Default Problems with Hygrophyla Polysperma

Hi guys!

I've some problems with my hygrophyla polysperma: leaves are curled and bended downwards (see picture below). I checked the pictures of the plant deficiency symptoms database, but I couldn't find anything similar.

The tank is a Juwel Rio 240 led that I set up two months ago. It's a low-tech tank without CO2, JBL Ferropol and Flourish Excel as fertilisers and it's hosting two orandas. I haven't tested all the water parameters yet, but I use half RO and half tap water (that is very very hard, GH>25F).

Thanks for the help

Polyperma is an excellent indicator type of plant.
Gets unhappy quick and can get better quick.

Feel for any other plants in there.

With what you are dosing no macro ferts are available for plants.
No nitrogen or phosphorus in JBL Ferro product.
And I'd bet little potassium in a micro fert as JBL.

Too much light PAR for a low-tech tank I reckon.
