Usually, the sediment is on the bottom of a tub and its white. It comes about when one compound in a nutrient reacts with another. the two products fall out of solution as a solid, which can give you a false sense security... you added Calcium a couple days ago, but it had an issue with Silica and now you don't know if you have any available Calcium or if its sand at the bottom of the tank.Thank you good sir, I now have 5 plants for the space, the smallest of the 6 is now under "experimental" category, as such ive had a bit of root slime, im pretty sure it was due to the light intrusion around the clay pebbles combined with Mg deficiency causing the plants to ge more venerable to it. 3 of the plants are now getting 254 gph of air to the roots, 2 are sharing a pump of these 2, 1 is receiving double hydroguard ( experiment ). And the smallest one is lure experiment, it is getting pumped out of the bucket and then back in every hour ( mild aeration) and has triple hydro guard.. I expected it to die.. its been 3 days and its actually grown quite a bit..
I expect to have at least 4 decent plants, though there have been a few setbacks, the root slime and the not soaking the rockwool properly being some, the lack of properly soaking the hydrotron In h2o2 being another.. ag deficiency originally mistaken for led light bleaching... ( never ever had a cal or mg deficiency in dirt.. total unfamiliar territory) sigh.. learning curves eh?
not sure why but I've also found that 2 ml hydro guard/ liter sprayed directly onto the affected roots is deadly to the slime but harmless to the plant, they seem perky afterwards thus far, i did this to the 2 experiment ones today.. might do this with regular daily p.h, tds and root inspections .. thoughts ?
A question i do have is this.
I am noticing a little bit of settlement in the bottom of a few buckets, its reddish in colour.. resembles iron bacteria. Low in the res, silty appearance. Am I correct in assuming these are dropped or un desolved minerals ? I mix with a mixing pump so I know they are mixed in properly at time of resovoir change.
Plants are drinking, tds is stable around 500ppm, one has gone down to 430ppm
Using general hydro 3 part + cal magic.
R.o. water
P.h 6.1 ( over 6 to promote calcium/mg uptake )
Hydro guard
Res temp 19.2 c - 20.4c depending on where i have the lights, I move them a few times during the day subtlety employing tipping them and dropping them over the day.. im logging this to maybe make an arduino mega with some actuators for light movers eventually.. I like robots
If you have any suggestions im all ears, if you need any specific info I can provide.
I have expensive thermal imaging. ( temp )
Same for humidity
Pressure manometer
Oxygen saturation testers ( for water )
And quality p.h. tester
Basically I can test pretty much anything air or water wise. I lack a par meter unfortunately though, and my tds meter is cheap as chips.. though it is my understanding that they al, do a decent enough job.. not as critical as potential hydrogen.
I also voice type so tend to have some rambles.. lols.. thanks for reading my novel here

Some things you can do to mediate that. There are nutrients that are more prone to reaction than others. The big three are Silica, Calmag, and micro nutrients. I wrote them down in the order they need to be added to the tank.
Silica can be a pain in the ass. If derived from Potassium its like a ratty child. It messes with your pH for days, but it NEEDS to be added before anything. You need to look into Silica,, if you choose to use it, YOU SHOULD, be sure that its made from mono-silicic acid. No Potassium!
Calmag, it can be an issue, but the way its made anymore make it much easier to use. Add it second.
Micro... micro can be just a additive or it can be part of a 3 part regimen like you and I use. Its full of metals and other stuff you don't need a lot of. Add it 3rd.
So, the above will help with elements precipitating out of solution, but you'll find someday, youll try a new product and you go t the white stuff in the res. BUT yours is red? Could it be shit from the media? I don't know dude
I'm gonna be starting a new thread in the near future... Should be 3 plants in RDWC, and 1 CBD plant in soil.
I'm going to be doing a new SCROG method i made up should be fun. Please join us
I will be advertising this momentus event on Smokeys thread if I dont tell you personally
