i set the room temperature at 22c day and 18c night , and that made the water temps 21c on the dot, so that's fixed, the plants perked up and they look better, i will be adding another air pump too, and i dropped some enzymes in the tank to help with the possible root rot, also +12ml of
calmag just to address those spots and the thing that looks like magnesium deficiency, we are now at 470ppm i hope it is not too much and it gets better, we'll see
Also, the plants are looking HUNGRY as shit but at the same time not taking any nutes...this has been confusing
