It went wrong in my thirty-eight. Brown, yellowing plants. Some melt to be expected as new ones adjust, but the watersprite and hornwort is all deteriorating which is an indicator for me. And crypt wendtii is all turning brown- some leaves paling out brassy and pink color, melting fast. Either it was the lighting or I messed up the ferts. I distinctly remember putting the dry ferts in the tank last friday, but not really sure if I did the micros. Did I forget? the browning leaves look like starved for nutrients, to me. I rubbed some soft brown algae off the apono leaves wed and put half a dose of micros in, just in case. But if I hadn't forgot the micros, that could be an overdose of something. Gah.
So I've reset the light up on its blocks (will fasten securely this time) and took off the plastic strip- left on just one sheet of the more transparent kind. Photoperiod is still six hours with two hour fade, both channels same. Nitrates were high, did the alternate dose of macros. Hoping I can turn it around and not loose all the new plants I just got. Kicking myself for not being content the way things were. Why did I think: hey this is good, let's make it better!? No- be happy when things go right and leave them that way.
Well, one plant seems not to mind anything that happens- elodea.
