Jungle val roots dying
For a year or two, I had a lush growth of jungle val. Recently, however, the leaves have been getting progressively smaller and I discovered that the roots seem to be dying back.
I upgraded my lighting to HO T5s over a year ago, and it seems to me the jungle val was doing better before the upgrade. But that doesn't make sense, right? The other plants (Amazon swords and cabomba, mostly, plus some surface floaters) seem to be doing well.
I use Flourish and an iron booster.
90 gallon discus tank
pH 6.8 - 7.0
2 HO T5s, one 6700K, the other pink (actinic?)
