Need Help Fast With The Brown Roots

what do i do im 1 week into flower ing and have brown roots on say 50 persent of roots on the bottem of the tray in a ebb and flow what do i do is this normal

Welcome to the forum ctec. Brown roots can be a problem if the roots are mushy. Have you noticed any difference in the way your plants look. You say 50% brown roots. Are you using the h2o2 we talked about? What medium are you growing in, sorry I forgot. VV

yes im useing 80ml of h202 in a 52l tank every day and im growing in a ebb and flow witl 4 inch with clay pebbles one inch cubs ill see if i can find a pic

If the plants are healthy looking above the clay pebbles then there is probably not a problem with the brown roots. Things to be aware of: the water temp can affect your grow, roots should not be exposed to light unless absolutely necessary. The h2o2 will kill any pathogens that would harm the root system. The ebb and flow system is one of the simplest most forgiving systems you can use. It sounds like you are doing fine and just don't know it. Pictures would definately help. VV

yikes - if i saw brown roots i would be concerned too...
never heard of brown roots being normal. is it clay resdue from your pebbles making them brown? is your resivor water "brown"ish?

nope the water isnt brownesh

Are the roots mushy? dejavu. If they are you must have to high of a temp in your reservior. If not..... VV

I've seen a situation similar to this... one of my local hydro shops was sporting a large ebb & flow table right in the shop's front window with six tomato plants (trees, more like) flourishing underneath an air-cooled, 600W HPS lamp. There was no hydroton in the table, only in the 10-inch mesh pots which housed the plants. The roots were spread across all four corners of the table and the mat was at least an inch deep. The roots themselves ranged from medium tan to dark brown.

I asked the guy who runs the store about this, as the plants themselves were obviously quite healthy and were fruiting bountifully. He explained that the intense exposure to light was causing the discoloration, as was the particularly dark nutrient bath he was using. He pointed out that none of the roots were fuzzy or mushy, so while they didn't look argent at all they were certainly healthy. Other than a few bugs eating leaves occasionally, the plants completed their life cycles without any problems whatsoever and produced several pounds worth of fruit.

with DWC this is nearly always light penetrating your bucket / tank and getting to the roots. this is particularly in early stages when the plant has little canopy and is very short and the light very close to the tank. Its best in these early days to put a thick bit of corrugated cardboard or wood or dark cloth on top of your tank to minimise light penetration. when the plant is bigger and more canopy these can be removed.

If your not running bennies get some Zone from Dutch Master, this will do 2 things

1 Kill anything that might be in there.
2 Prevent anything from starting.

The biggest factor in any root problem is STRESS, yes stress, if your plants are stressed they are more likely to have root problems. There are other things that contribute to root issues like, Water Temp and cleanliness but research has shown Stress is the number 1 cause of Root Issues.

acheck rez temps. they should be no higher then 68f , if higher then 70f its root rot.

Go to your local garden center and buy a product called Pondzyme with Barley. This stuff has saved me. It costs about $15 and last you 8,000 gallons. You only need a very small amount every 2 weeks. I use it all the time now and have not had any bad roots or bad reservoirs in long time.
