What is wrong with my roots and one plant??? with pics!!!

I dont know what is wrong with the roots on 2 out of my 4 plants....they have brown slimy spots on them...??? I am using General Hydroponics Floracious Grow nutrients right now...so i dont know if that has any thing to do with it or what?? and the plant in the picture was growing well and then it developed these burn spots and then it started to get dark green areas and now this is what it turned out like...the new growth shoots are like burned and yellow...and this is only to the one plant out of the 4 so i dont know what it is???? Someone please help?

looks like ur letting light into ur res/bucket could be alge,+ if that is the case ur roots are dying as they can't uptake oxygen

No there are no light leaks i just pulled the lid off to take the picture...and i set it onto a bucket...

Just because the roots aren't directly under the light does not mean they aren't exposed to it. it looks like your res is yellow in color it could b letting enough light through the plastic to cause algae. Try wrapping your res in duct tape.

My resovoir is dark gray and light cannot pass through it....

Go to walmart and buy some BLACK ducktape. Wrap your res AT LEAST twice with it. Trust me, I thought I didn't have light either in a BLACK bucket... I was wrong. Also, try topping up your res once in a while to submerge the roots at the top. Even the slightest bit of light can grow algae.

ok thanks i will try that out.... and any suggestions about the plant burning and spot???

anyone???

Do you have them on any nutes at all? If so I would put them on a 1-1-1 ratio for a week or so more then switch to stronger nutes.

they are on nutes right now.....full strength floracious grow....

I would switch the solution to something a bit less potent or maybe even just straight ph balanced water until the plants start looking healthy again. Hydroponics is a very delicate process and not nearly as forgiving as a soil grow. If this is your first grow I would try taking it slow using 1/4-1/2 strength nutes so you don't get any burns. Not sure on 1/4 or 1/2? Go with 1/4 to be safe then. Asthey say better safe than sorry.Go buy/download/whatever a copy of the Cannabis Grow Bible by Greg Green or a copy of Marijuana Horticulture by Jorge Cervantes. Either has a whole section dedicated to hydroponics with a lot of info on DWC setups also. Those two books are meant to be used basically like a manual... You start your grow at chapter one and by the time you harvest you should have a decent crop and know most everything there is to know about propagation. Don't like to read? Then what are you doing on these forums!? Nah I'm just playin. But if you really don't enjoy reading go get a copy of Sir Jorge's Ultimate Grow DVD. I have read/watched all three of these and they have proved invaluable.

That's a 5 gallon bucket that it's in btw.

ok thanks....
