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.

Extremely slow vegetative autoflower grow. I'm growing Glue Auto from FastBuds and Dark Devil from Sweet Seeds. What is wrong with my environment?
I'm currently watering about every 3-4 days, one time just water the other nutes from CANNA at 1/4 strength, temps between 20-27 and humidity about 60%. Glue Auto is about 30 days, Dark Devil is about 1 week. Oscillating fan is always on, extraction fan only turns on when >60%

This is a short video of the Trichomes on my Fastbuds Bruce Banner Auto. I'm 79 days in, the estimated harvest is 70-77 days. I was shooting for 40-50% amber. I'm of the opinion that I can let her go for maybe a week longer. Any opinions?

Harvest time
It's been around 8 weeks since flowering and to me the buds seem ready. However, these white pistils keep appearing and makes me think thank it's not ready. What do you think ? I also started watering just plain water, but i think i should go back to adding nutrients.
