I haven't expressed myself well, should I remove the mold or leave it? It's my first time with mold on earth. I added microvita from top crop, I don't know if it has anything to do with it

Calcium in tap water
Is 95mg/L calcium too much in tap water? (It's probably a little lower than that, since that's exit measurement from the waterworks.) I haven't seen any signs of acute calcium toxicity, but I'm worried about buildup.

1841PPM
So is an 1841ppm solution ok for a plant? I figured since it's in Flowering it should be an OK input, normally my ppm readings are 1240ppmish

Water Info
What water is everyone using? I've been using spring water at pH 6.5 because my taps reading 8.3. Should I purchase a pH up/down? Also I'm growing in soil & heard pHing is not necessary just let tap water sit for 48hrs? Any information is appreciated Thank you

Humidity too low, any ways getting 60% without a humidifier?
I am struggling to get my humidity high enough as it keeps trying to fall to 30-40% and I'd like it to be above 60% - any good tips how to do this and how much it will affect the plant? Laundry hanging near tent gives ~10%+, I've also tried misting some water every few hours.

Tell friends
It's my first hydroponic planting. Cookie R2 has 9 nodes in total (I even thought it would die) The biggest mistake is making the cold water alternate to normal temperature, causing the plants to stunt. I thought for a long time that the trunk was so small.

Dehumidifier recommendations
Any recommendations about a dehumidifier for the 4x4 grow tent? I think even with vacuuming run-off more frequently, I won't be able to get humidity consistently down below 60%. Amazon has some in the 45-90 USD range...
