Since I have most recently replaced my old t-8 single bulb lamp fixture with a 48" beamswork DA 120 6500k I have noticed new growth in my Bacopa, I'm getting new growth popping up out of substrate beside Bacopa stems as if seeds were planted (GREAT). The leaves on my ludwigia have stopped falling off (GREAT). The other thing I've noticed is it seems as though my wisteria has slowed down. My maintenance has stayed the same and my dosing regime has stayed the same, my only change was lamp fixture? Maybe I'm just watching too much? New growth coming out of substrate and leaves no longer falling off are easy visual signs but on wisteria it seems to have slowed down. According to directions for dosing regime I should be giving more than enough liquid fert. Maybe some plants have some type of growing stage where they'll grow a lot in one month but then slow down the next? I'm not quite sure what to think. My algae growth has increased. Has anyone experienced intermittent growth spurts with their aquatic plants?????
