Brown crud in hydro
Chow_13answered grow question 4y 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.

How much longer do you think?Mother was chopped at 65-75 days and looked like these buds do. This clone is on day 45, buds seem more mature at 45 days or maybe just fatter due to better care. Buds have some ambers already, started her flush this week. Is bud sweetener(ff bembé) okay to feed during flush?
