Brown crud in hydro
Chow_13answered grow question 3 years ago
If its not smiley it's most likely a nutrient/mineral buildup. I use regular tap water and get that with general hydroponics. It would usually be white but the nutrients stain the buildup brown.
Happy Growing

If temps are in check and now slime or smell then it’s just nutrient build up.
If it smells really bad then you got root rot starting up.

Seeded flowers? Just checked my auto tent again. At least one if not all of the plants appear to be seeded. I want another set of eyes to look.I dissected one of the flowers and saw what appeared to be a seed at about 2 weeks of maturity. So still very young. If you do see signs of nanners or seeds, please go through my growdiary and pick out what I did wrong. I cannot identify anything happening this grow that was bad.2 years ago
