Hydrocotyle Leucocephala / Mushroom Pennywort

[gzylo]

Hello there


i`m not experienced and this is first time i have this plant. in my friends tank it was proper live green. In my it starting to go white on new leaves, is it lack of iron in the water

p.s i do fertilize with tetratec plantamin + have co2 - not pressurised
