Help beginings of root rot?? 22 day old Blueberry DWC

Here is my 22 day old blueberry, she was very aggressive in the first 18 days of life she has slowed slightly and the leaves arent very perky, and not a uniform green. is this the beginnings of root rot?? my grow box never gets above 75 and my soln doesnt get above 68, i have a dual outlet air pump with 2- 5"air stones , i have the unit lightproofed and it holds about 2.5 gals of nutrient soln which i put in 4 teaspoons of fox farm grow big. i have no way of testing my pH here are some pics what do you think??? also i am about to order fresh nutes, thinking fox farm Hydro Trio and Cannazym and a ph control kit. started this grow on a whim and it went pretty good so any ideas so far??

put a teaspoon of hydrogen peroxide in the res. and make sure the water isnt too warm or any light is gettin in

how strong % of h202 should i use??

didnt know it had a %.... just go to target or walmart and buy the regular bottle of Hydrogen peroxide? as for percents i couldnt tell you

yeah its has a %. also i heard you are not supposed to use hydrogen peroxide with organic nutes. Fox Farm are organic based does this make a difference??

soak roots in the peroxide if you can or can apply it in the reservoir then i recommend this stuff called hydrobact great stuff for hydro only,watch your reservoir temp and no light penetration it doesn't matter if its organic or synthetic nutrients hope that helps

Root rot occurs from lack of oxygen in the water so the roots suffocate and rot. Water holds more oxygen per liter at colder temperatures. It wont matter how many airstones you have if the water cant hold it. Don't let water get to 70F. Maybe some icecubes in that bitch.

I think you got too much nitrogen in that there batch... There too green.

Follow the fox farm feeding schedule.

Works great for me.

G'luck man

good point growing 4 gold I was just about to say that people always get them cheap pump thinking it can sustain enough oxygen for the roots not so maybe for cloning but not for growing with hydro you have to have the right equipment before you start and believe me you need the proper equipment thats why im back in soil until I afford the rest of things i need to be successful in hydro

thanx for the input guys im keepin a close eye on her and hoping for the best, im goin to flush the rez and put straight h20 for a couple days and see if she straightens out if not i will have to try h202.

I agree with Closetgrow. A little heavy on the grow big for such a young plant. And the peroxide % you are looking for is 35 or higher. The drugstore peroxide is far to weak to do much good. If you are just using grow big then no worries using it.
