i just had the same problem. its due to the heat and its cald pythia. if u r adding sugars or any carboload, stop . get some hygrosime do a compleat flush add 10mls higrozime per gallon of water and give it a few days. the microbs will feed on the muck and digest the dead roots , thay will be wight in no time. u might check ur rez temps.HELLLLLP i just looked in my 5gal dwc bucket and my roots seem to be starting to have brown shit on them the night after a res change. what can i put in the bucket to make them back to the white girl
if u use the gh flora micro bloom...it stains the roots....pics would be nice...well i just changed the rez out pretty much yesterday so should i change it again and put this in there or just add it to the rez
h2o2 kills everything in your rez. and then all of the dead roots that were rotting are just going to sit there and start to rotte again . u need helpful bacteria to digest dead or rotted roots kinda like a micro maintenance system.no h202....kills helpful bacteria
cooler is always better. but if u cant afford a chiller, then u need to be able to work with it. my rez temp are always in the 70ish range. i found that when it gets warm u need to stop with the suger's , that feeds pythium . also when it is warm u need to up your air flow, more air stones. get that water moving , i just added a 70 liter per min pump to my system , when i turned it on i looked like the water was boiling and i still add 4 more air stones .hygrozime is the ticket if u are not using any microbes in your feed get some hygrozime. do it for your plants. they will thank you by being big and healthy.I find that 70º is the point where pythium can start to form
68º gives me a small margin
and that is why I run 66º
