How can i check if i have root rot

im having problems whit my seedlings how can i check if i have root rot,or some root problems,the conditions are all ok im trying to find out if its a disease or something like that

Dude, I've seen your pics and I think you got some kinda deficiency. You don't have root rot.

thats impossible,now i have 15 new seedling beside these and after 8 days they start to show same symptoms tips of the older leaves start to turn brown dry and it spreads,how can it be a deficiency and all the other plants were fine before,i checked the soil so to be sure that its not to strong the n-p-k of the soil is 14-16-18, 0.7kg/m3 ph 6.5,im fliping from this shit and i cant figure out what it is im thinking tomorow to take a sample to a lab to see if its a disease

ph soil 6.5,ph water 6.5, temp 24c day 20c night ,humidity 45%, cfl 23w for 10 days and then 430w hps

if your grow medium smells like semi rotten patatoes u have root rot or if your roots a dingey or brown

No man..... having an intelligent conversation with you is impossible. If your leaves are yellow.... that's whatcha call a DEFICIENCY. I don't care if something is locking nitrogen out... it's a deficiency.

You're asking people who don't grow your plants what's wrong and I'm telling you it's not root rot.

thefaux are u telling me there is no possibility that a cannabis plant can have a disease

No. I haven't even hinted at anything that resembles that comment.

drop your ph to 5.5-5.7 6 is too high too much alkaloid prevent nutes to absoarb through the roots.

but everywhere they say for soil u should kepp it between 6.2-6.8,thefaux listen why i dont think its a deficiency.how can a plant have a deficiency after 8 days of life plus in this same soil and conditions i grown 1 pack 20 seeds outood mix,1 pack 20 seeds indoor mix,skunk #1,early skunk,northern lights, afghani,all from sensi seeds and had no problems,and now i palnted this lr/ak47 and after 10 days 2 plants start to show these symptomes,then i tought that it was a deficiency or a burn so i added some fert 14 strenght but that wasnt it,then i flushed 3 plants of my 5 but that didnt help so i thought maybe its the strain,so when i planted purple haze and euphoria they were fine for the first 8 days and then it started whit them too first the purple haze then the euphoria now from my 20 plants i have 12 that are contaminated,i checked in the store where i bought the soil but they said that thats not possible and this doesnt make sense couse in the same shit i used to grow those plants whitout problems and now this is happening,if its the soil or the water or something like that how come not one of those plants had a problem,so today i gave a sample in a lab to be tested and to see if its a disease,but thats monday when im gonna get the results and thil then my plants are gonna be screwed so im trying do to at least something, on 5 i tryed a fungicide

have pic? It is more helpfull to ur benefit

1/4 strenght

these are a little old,today il post some new pics of the small seedling their leaves look some different from these thats how it start i know that this looks like a deficiency but when i gave nutes to 2 of these 5 it didnt help,i had a deficiency before i start whit the feeding and they just grow but this is something different

not enough perlite what kind of soil?

https://www.rollitup.org/view.php?pg=faq&cmd=article&id=171 here ya go also one major factor in the "it didn't happen to my other grows" is because its all diffrent strains.diffrent plants require diffrent things imo some like a alot of nutes others dont maybe them strains are sensetive to what you are doing

I just don't think it's root rot because it's usually only a problem in hydro. For roots to get rot in soil they'd either have to have..... A) been planted in contaminated soil or B) been over-watered in a HOT environment. And because it's happening to so many plants it's just that much LESS likely to be root rot.

Maybe you've got too much of something locking something else out. Some of my leaves look like that but they are under the canopy in low light conditions and I feed them heavily.

All I can say is I'm 99.8% it's not root rot.

You use R/O or tap? If tap..... do you know what the EC and/or quality is?

If you really think it's some kind of microbe infection I'd recommend SM-90, but I just don't think it's going to help your problem.

my tap water is ph 8.2 i lower it to 6.5 using lomon juice tomorow im gonna get some ph down, 200 ppm,i do have perlite i covered the surface whit pure soil couse i have some organic fert that stinks so this way it smell less

when i posed this question of root rot it was more out of a desperation couse i cant figure this out and its killing me,but the plants first
