Hygro yellowing
I'm also a newbie in the field of aquatics. I've had a 20gal for about
4 months now. In my tank I have java ferns, anubias var. nana, crypts,
and a hygrophilia polysperma which I purchased about a month ago. The
three stems have only sprouted a few small leaves at the top, but these
are beginning to turn brown. The older leaves are yellowing and one
leaf has even turned brown and is rotting. I am wondering why this is
happening because the rest of my plants are doing fine -my crypts
produce a new leaf every week or so and my ferns are a vivid green. I
have heard people often say they use their hygro as a 'canary' and if it
isn't growing properly there is something wrong with the tank.
Just for the records, I haven't checked the water for many levels but I
do know:
ph=6.9
CO2=diy injection (directly into intake tube)
hardness=moderately hard
fertilizer=PlantGro by Flora Care
What's going on?!? I'm worried about the rest of my plants and fish...
Thanks in advance,
