Root rot???

[AirBuds]

Leaves were started drooping just 2 days ago and yesterday I flushed with RO water with 6.5 ph. I ran 5 gallons thru 3 gallon smart pots until I got the ppm down to about 150.
First i thought it was from the weather change that cause my temp inside my tent to drop from 68-78f degree range all the way down to 60, and my humidity dropped from 40-60% range to as low as 28%. I bought a small humidifier that has my temps and humidity back up to normal levels but did not change anything with the plant as I'd hoped. Just from doing a search and reading about several things it could be, I think it's root rot because of the drooping top leaves and the small brown spots that I've found on 2-3 lower leaves.

Hi airbuds.. i see you worried about your babies. The led pic wont help me or anyone because of the light. i can see the other pic and its looks water logged from the flush im sure. id like to see full pics without the led so we can see issues. I don't think your dealing with root rot.
how dry are you letting the soil get? let it get real dry before another watering..

I am with Elvis on this one, I think that the drooping you are seeing is from over saturation from flushing and they should perk back up in the next few days. They look pretty healthy to me, other than that wierd hole in the one fan leaf that is kind of strange. Have you checked for any type of bugs or little critters roaming on the underside of the leaves? Also just out of curiosity why did you flush? Are you switching to Bloom nutes? The reason I ask is because the down turned leaves and the slight yellowing that is starting in the 2nd picture might be a nute deficeny of some sort( I would guess N) But that is a secondary suggestion, as I stated earlier I just think they are over watered and will be fine in a couple of days. If it doesnt you might want to take some good pictures of any affected area without the LED light on and post it in the AFN Live 24 hour Help thread, it will get a lot more eyes on the problem than in this post. Hope this helps, sending mad grow Karma your way.

well if its an Auto thats fixing to flower your ppms should start to increase slightly so imho thats not an issue.unless it was waaay up or something maybe.but drooping leaves are pretty normal as a rule and the brown spots you see developing(since your under LEDs also)is most likely cal mag creeping in on ya.but it seems more droopy cuz of all the water too and it cant breath well enough.i would stick them on some small wood blocks or something and put a fan under them and get the temps up to roughly 73 or so to really bring on some better plants.colloer will slow the growth and shock the sun leaves as a rule especially if its an abrupt shift in temps.

if you can stick your pinky in the soil all the way down and it comes back not slimey at all you have no root rot at this early stage.your pots been drier recently?if so ya aint got root rot.let it dry out with the fan for a few days and hit it with a small sip of cal mag once its dried out some,i personally would not add any extra water at this point.let them roots breath some.

Hey all, thx for quick replies.. I'm out of the house now but will take some pics with better lighting but that's a relief if it isn't root rot. I took a magnifying glass and check all my plants and no tiny bugs or anything. And I'm using OF soil and I added some nutes not really knowing that I shouldn't have. So when 1 got a little nute burn, I flushed it. then did a flush on this one bc I thought the small brown spots were from this one starting to get nute burn also so I wanted to catch it before it got bad or anything.

Also I have my pots sitting on milk crates which is on top of a pallet so the air can circulate under them.

As for watering, I'm waiting until the soil is dry and crumbly on the surface and doing the lift test, then watering the next day. That's usually 3/4 to a gallon every 4 to 5 days.

usually under leds ya get brown splotches that are due to the leds pulling out the calcium and magnesium some so.higher temps will include potassium as well.but nute burn early one will almost always appear on leaf tip prior to anywhere else.clawing of leaves n so forth.that can be a crazy little ride. take some in natural light with a flash and if you tips are good (since you only feed a little bit at 50% strength as autos require earlier on in life..?)im thinking cal mag.but untill then...lol hope that helpful man.

yeah man I had one of those weird holes show up on a leaf recently... Turns out the culprit was another cannabis plant that got me too stoned to remember the importance of careful handling LOL

Responding to OP... If I had to guess, from those two pics I would be inclined to agree over saturation and likely some sort of deficiency, both from early stage flushing... I've ben using liquid calcium no mag on my coco recently and just treated a magnesium deficiency. Nitrogen or Magnesium deficiencies, either one will benefit from some Cal/Mag... Extra air around the bottom of the pots can help them dry faster...

peace, I'll be tuning in!

I see that you're using OF soil. Have you checked the pH of your run off, and if so, what is it reading? OF can have a very low pH, some bags as low as 5.5. If you got some with the low pH it's quite possible you could run into some issues related to the low pH.

Yes a few weeks ago I had run off ph of 5 and u told me to add some dolomite lime and run off is now between 6 and 6.5.
