Root rot or unbalanced ph?

Strain: Unknown
Medium: Soil, Indoors
Growth: About 5 weeks flowering
Nutes: Generic blooming agent
Watering schedule: Watering schedule was always around every 2-3 days, although i recently flushed and the soil stayed wet for a whole week. After that week the watering schedule went to around every 3-4 days.
I Flushed because of minute signs of nute burn, and after that it went back to perfect health. I have been watering with 6.0 ph water. 2 weeks later these symptoms show up..


I would have more pictures but this is the only leaf that has really progressed this far. the other leaves are showing very small signs (small brown dots) and there is no sign of this at the tops, only middle and bottom parts of the plant.
Anyone ever have this issue before? Kinda worried

"flushed becuase of minute signs of nute burn" <----- no. dont flush becuase of small nute burn. just feed them plain them for a week. only flush if theres serious toxicity and the plant will die otherwise. flushing is not good for a plant, not good at all. your basically choosing to drown a plant, and should only do this becuase if you dont, it will overdose. get what i mean?

"I have been watering with 6.0 ph water". well... not quite. water is 7.0, so 6.0 water isnt really water. also, if your in soil, the 'liquid' you add to the plant should be at 6.8, not less.

"[picture]" that pic is NOT nute burn, thats probably a phosphorus deficiency, especially if your flower. meaning flushing made it worse. add some bloom nutes, and up the micro nutes.


nute burn is death, burning of the leaf TIPS, not the middles, and not sporadic like that. its on the LEAF TIPS, the serrated edges, going all the way around the leaves, the center of the leaf is the last to see damage. your picture is NOT nute burn.

Sorry that was a typo, ive been watering with 7.0 ph LOL not 6. And i agree with not flushing if the nute burn is minute, although i feel like it wasn't really minute since half the bottom leaves were completely burned and feeding it just water for around a week and a half wasn't helping it much. After the flush the health greatly improved.
But i did not come to the conclusion that it was phosphorous deficiency ill take that into account probably up the bloom and micros. Thanks

completely burned? wait wait. the bottom leaves die off, thats normal. they will turn yellow and dry up and die. a few leaves, 2-3 at a time, per week or 2... thats cool. they get less light, and the plant doesnt need them. from the pics, i dont think your nute burn was that bad. especially in flowering, the fan leaves take a beating since the plant cares less about them.

When the nute burn occurred the plant was barely into flower, and i know what nute burn is although the plant has been shedding its old fan leaves as expected and im obviously not worried about that. Im more worried about the possible phosphorous def. that you indicated.

If you are worried about root rot, or Pythium fungas, then carefully upend and remove the pot to check the roots. This is easiest to do when the soil is fairly dry. They should be a nice bright white color. If they are a tan or light brown then you have root rot.
To treat root rot you will need to treat it with H2O2.

h202 works with soil as well huh? I know its not the best to use in a hydroponic systems, especially if your using organics.

Would it be easier to do a transplant into some new balanced soil?

I think I'm definitely going to remove the pot, and check the roots. That way i can check if my roots have enough space as well and aren't root bound.
If my plants are discolored and i indeed have root rot, would i need to remove the damaged roots or just administer h2o2?

Nute burn shows up on NEW growth, not on the lower parts of the plants!

Now that we got that out of the way, you stated that the lowering leaves drying/dying off got worse with with you only feeding water for a week and a half didn't help, well no doubt! That was a sign your plant was straight up hungry and NOT burning! If everything else looked good, you just needed to feed it a bit more by the sounds of things.

You have now created several issues by jumping the gun and not getting any advice a bit earlier imo.

i'm sorry. it's aids

Hey look, you managed to attract a troll......

root rot resembles nute lockout due to the fungas damaging the root system, making it impossible for the plant to take up the nutriants via the root system. The plant will try to get its needed nutriants by canibalizing the lower fan leaves. Adding more nutriants does nothing to help, as the roots cannot uptake the nutriants it needs. Flushing with plain water only makes things worse, as the fungas will just keep growing and damaging the plant. Transplanting will do nothing as you would also be transplanting the fungas along with the plant.

Hydro stores sell a 29% hydrogen Peroxide solution for less than $20.00. Using 5 ml. per gallon of water to soak the soil in the pot will kill the fungas. You will need to re-introduce the good bacteria into your soil after this is done, as H2O2 also kills of benificial bacteria as well as the fungas. I do this by brewing up a Earthworm Castings Tea and feeding the soil with it. I do this after the soil has dried out from the H2O2 flushing.

Thanks for that! That will definitely be my course of action as soon as i can figure out if i indeed have root rot since i am away from my plants until tomorrow.

I feel like it is though, i read somewhere a sign of root rot is a retarded water intake and ive had to slow down my watering lately.
Thanks for the info

A sure sign of root rot is discolored roots. If they are brown or tan, then it is Pythium fungas or one of the several other fungasas that are called root rot. One thing I should have mentioned is that if you treat with Hydrogen Peroxide is that you should get the 'food grade' or the stuff they sell at the hydro store. I heard that the 3% H2O2 that you get at the drug stores has a stabilizer in it that will harm the plants. I've heard that in a bind it can be used, but its not recomended, and I don't know the proportions it should be used. I treated some badly affected plants about 2 weeks ago, and the next day the difference was amazing. Trim off all damaged leaves, as they will not recover.
Good luck and I wish you well with your grow.

I recently checked on the babe, and shes doing great. I also checked for root rot and thankfully i don't have any. The roots are a nice white color. I think the slight spotting and discoloration may just be accumulation of a few things like nute deficiency, maybe genetics, and the plants natural way of flowering. Here is an updated pic 3 1/2 days after the first original picture was taken.

And here's a blurry pic in the dark
