Has anybody else observed this? I can't find BGA anywhere else in the 45 liter tank, but only on some (not all) tips of R. indica. Does the plant leak nutrients (ammonium?) from the apical meristem?
I've had this plant since 1999 and only observed this the last few days. I did some major changes right before this happened, though! After a long period of more or less neglecting this tank I finally got ingredients for making more PMDD. I tuned the PMDD to give about 20 ppm NO3, 30 ppm K, 1.3 ppm PO4 and 1.2 ppm Fe (most of it chelated; HEDTA, DTPA and EDTA). Also some micros and Mg. About 30 ppm CO2 (off during night). 2 x 18 watts NO fluorescent tubes with reflectors.
Earlier when I have PMDD-ed, I used less nitrate (5-10 ppm) and didn't add phosphate.
It's not a big annoyance, actually, so I don't think I'm going to do any big changes - at least not before things have stabilized a bit more (maybe it will disappear by itself?). Just wanted to hear if somebody else have experienced this, or have a clue why it occurs ...
