brown build up in my hydro tank what is it?

i have 14 plants going just normal good homegrown seeds they are 11 days into transplanting stage i am running two 8 gallon hydroponic bubble systems and three air pumps running 4 airstones they have been running non stop for 11 days now i am going to change and clean the water at day 14 with diff nutes for the next stage just curious what the brown stuff sitting at the bottom is just dont want that to be the nutes they are suppose to be getting now. Also i would like to know how long to leave them in the second stage i have my second set of leaves on all 14 plants showing they all look great are about an inch to two inchs tall like i said before i was going to change water and nutes for there next stage in 4 more days to soon or am i in good shape?

mine was alwasys real bad about that when i used my well water. i think its like the sugar in the tea thing, just a little too much and it falls to the bottom. long story short you might have some overloaded water or your nutes might just be settling

ok cool just my first indoor grow and i wanna do this right i mean i have spent hours trying to research to make sure i do this by the numbers and what the pros have found that works everyone told me to grow with dirt ima prove them wrong haha i have a really good setup just got learn the indoor ways

Most of my first grows were hydro and very successful. Just read and follow the facts and dont let anyones ignorance hold you back.

it should be settling if you have your airstones going ..

hey are u useing the type of systems with hydroton sitting in the mesh pots?
if not sorry im baked, but i noticed the same thing and it was because i didnt wash the rocks off before i put them in the water.
turned my water brown for sure
