root rot?

I purchased a very small 10 gal. dwc system, does anybody know if this is root rot ? 1 plant already died, I tried giving multiple warm nutrient baths but it doesnt seem to be helping. I read an article that said to add pure un-sulfered and un-salted molasses to your nutrients. mabey the water is too cold and the molasses solidified on the roots?.

ideally the roots should be white, no matter the medium. brown roots cant be good.

also, if the water is cold enough to cause molassas problems (doubt possible), its probably too cold in the first place. the water should be room temp.

I purchased a very small dwc tub system and the plants are dying. Iv'e tried multiple warm nutrient baths, peroxide and several flushes and nothing seems to be helping. I dont have enoufgh power to run multiple aquarium heaters, so the water temp. is a little cold. I made a 30gal. version of the tub system and there all doing excellent. I recently added some un-sulfered and un-salted molasses to the tubs so mabey the molasses solidified? or is this simply root rot?

i answered this in another forum, so stop multiposting

Is this root rot?.

Roots won't always be white. The use of organic nutrients and additives will usually cause browning of the roots and this is no problem; however, the roots in the picture are not in good shape.

Molasses is very likely the culprit here. On these boards, I know of two people who have posted about molasses use in DWC: Weedhound and myself. Both of these attempts were met with horrid results. This is a picture of mine after molasses (note the resemblance?) and here is Weedhound's post. I don't think there is much you can do for them at this point; they'll either grow new roots... or they won't. I stopped using molasses (obviously) and started using Botanicare's Hydroguard. Instead of molasses, pick another carbohydrate supply, I'm using Botanicare's Sweet. It's more expensive than molasses, but it doesn't F%#* my stuff up :)

You need to drop your pH in a hydroponic setup to circa 5.8 (+/- 0.2). The temperatures are probably not a problem. Cooler water will hold more oxygen, providing a better atmosphere for the roots. Obviously you can go too cold, but I stay around 65degF.

Making 3 threads on the same topic is very poor form :wtf:
I have merged them so that all answers will be in the same place.

I apoligize fot the multiple posts, I'm new. I'll pay more attention next time, thanks for your patience.

Thank-you for the info. Someone suggested SM90 for the rot/fungus so I think i'll try that.

I know your not supose to post twice, but we've lost 3 more plants and I've tried everything that has been sugested. Original post is under root rot 2.......thanks
