Hard water calcium build-up. Should be fine unless you want to add filters on your water source.

Correct, just dried out nutrient salts/calcium due to evaporation. Nothing to worry over.

flash photos in the dark hours
I got a doubt (probably very stupid) and it is: photographing the plant with the flash in the dark hours do not risk confusing and stressing it?

Light intensity? Should I dim?
I'm having a light-science question. I have 5 bulbs, 11w each, total 55w. I know this is not much but anyway. Should I dim the lights for seedlings even If I have this low setup? I mean, does light intensity affects seedlings' health? Or 55w can work on a maximum level?
