Help with yellow leaves!

I hear you, just know I thought they were under watered too for the longest time and started to water them every 2 days because they looked like that every two days. They would perk up, I would be happy than in 48 hrs they would be terrible again. My roots were rotted to shit when I finally took the plant out to re pot as that was my final option because the plants were in such poor condition. But hey, do what you think is best, its your plants. Took 14 days to dry that shit out in a new never been watered pot with new soil. I cannot find the really bad pics i must have deleted them but here is one where I had the issue, but in this pic they were no where near as bad as I they before.

Dude, you are giving poor advice. Your plant does not look like that because it is over watered, it looks like that because it has root rot, which prevents oxygen uptake. Over watering isn't even a thing in a well built soil, it is just you flushing nutes out of your pot. Otherwise please explain hydroponics to me. Cheers!

 

[crimsonecho]

Are you feeding them anything?

You either have an overwatering or underwatering problem, at least seems like it. Both causes problems at the roots. Then you flushed with water right? How much water did you use? Because flushing is not a good practise imo. It also messes with the roots and strips the readily available nutrients from the soil depending on the amount of water you use. Just give them a bit of time. If you have a root booster at hand i’d use that.

 

[polishpollack]

Bugeye, how do you know it's root rot when we haven't seen the roots? The discoloration could be cause by any one of a number of problems.

If you overwatered your plant, to give some time to them in dark period would be helpful. Turn off the light for 12h and then check it, trust me it works well, if it dosen't give them more time in dark. There are some studies, plants are giving more attention to the problems about soil and roots when they are in dark. I was read some scientific articles about it and I saw it really works.

And what do you think causes root rot? ummmm over watering....What do you think prevents oxygen uptake by the roots?ummmm over watering..... Over watering isn't even a thing in well built soil? Dude whatever you're smoking is hurting you mentally. I am literally telling you I over watered the plant, I am not even trying to defend it lol. You are dead wrong about no nutes in the soil as the ppm run off of those plants WITHOUT adding nutes was high 600ppms FFOF fyi, you do not know what you are talking about. I am telling you I over watered them and you are telling me I didn't lol. Just for the record I never flushed any plant. Look up what "flushing means". It does not mean over watering, it means you run gallons of water through your medium to FLUSH the soil, coco of salt build up. I literally have never done that to any plant for any reason. Over watering is the #1 problem for new growers by a mile.

I apologize for being over provocative, perhaps rude is a better word. Sorry.

May we now engage in a civil discussion on "over-watering". If providing too much water to a marijuana plant is harmful, hydroponics would simply not work. As you know, hydro works because the water is saturated with oxygen. So we are really talking about a lack of oxygen in the root zone when people speak of an "over-watered" look.

In soil, when someone says it looks like you have over-watered your plants, what I hear is, you have not provided your plant with an ideal soil structure. Most likely there is insufficient aeration elements in the soil or too much clay, so the soil holds too much water and not enough oxygen. An ideal soil structure will hold both water and oxygen and have high levels of beneficial bacterial that will not allow root rot to take place. An example would be a base soil structure that is 1/4 loamy soil, 1/4 coir (excellent water retention), 1/4 large perlite (excellent aeration and water retention), and 1/4 worm castings (excellent bacteria and good soil structure = no root rot).

A base soil mix like this has excellent drainage and excellent water retention. When you put water down on a soil like this, you are pushing old air out and pulling new air in behind it. So watering becomes the delivery mechanism for air exchange. In a soil like this you are only over-watering if you put down so much water that you get excessive run off, which is stripping goodies out of your soil. A little run off every now and then is good for purging salts, but lots of run off on every watering is just stripping nutes out of the soil.

The "rules of watering" seem to have been developed by people growing small plants indoors and do not hold up to large plant outdoor grows or greenhouse grows where heat can go higher than 80 degrees. I will offer up some photos of my plants that enjoy a daily watering every day of their lives. It is not important but I have been growing weed for 20 years, indoor, outdoor, greenhouse, synthetic, organic, hydro, soil. So I'm not a newbie. I use to share your beliefs on over-watering, but I've learned it is a more complicated story than that. In general, if a plant looks wilted and the top of the soil is bone dry, it is wrong to assume the plant is over-watered, especially when you can see lots of perlite in the soil. Cheers!

The person who posted the photo of the plant with root rot specified that the plant had root rot. Presumably he examined the roots.

Not even going to read the essay you wrote. I am going to assume it’s you trying to prove me wrong. Ok, you win, over watering doesn’t exist and it’s a myth, I will move on.

Ok, good luck with your root rot.

 

[polishpollack]

Bugeye, I wouldn't presume anything. Presuming roots have been examined in a soil grow, if I understand this one right, is silly. Bad move.

Don't you examine your roots at transplant? First thing I would if I suspected it.

 

[polishpollack]

I had a feeling you would bring that up, the issue of transplant. Not great argument. My point is that you said root rot even though the grower never showed roots. So how do you come to that conclusion? Gibberish. Root rot is usually Pythium root rot and tends to occur in hydro, not soil. It can happen in soil but using a sterilized potting soil reduces that possibility to zero. And your idea of overwatering not even "being a thing" in well-built soil is silly too. If any kind of soil doesn't dry, air (oxygen) won't enter the soil. There has to be a cycle of wet and dry in growing plants. We can see from an early photo, post #13 I think, that the soil wasn't being watered enough. No root rot in dry soil.

You are conflating a side discussion I had with jtrizzy. He posted a pic of a plant that he said had root rot. I never commented on the OP plant, which clearly just needed to be watered. But do explain how hydro works if a dry cycle is needed. BTW, guys that get root rot in soil are using poorly constructed soils.

 

[Bugeye]

@polishpollack - Some of my plants in their "dry period" or afternoon as we call it. Drip lined every morning because they wilt if they don't get it. They never show an "overwatered" leaf structure. My soil is built for superior drainage and excellent water retention. The only rule of watering is do it when the plant needs it. Obviously there are too many variables to have a nice neat little watering rule we can all follow all the time. Learning to read a plant is the goal.

 

[redivider]

well I'm going the nute deficiency route.

these photos look like a Molybdenum deficiency....

yeah I said it.

whatever PH you are using- go a touch higher - and I mean just a tenth or something, ease it up just a touch.. you can also do a very light dilution of the nutes and spray them..... find how to do a foilar feed with those nutes and spray it down....


Google Molybdenum deficiencies and compare to your plant - it's a deficiency that looks almost exactly like an N deficiency but with some necrosis spots and I think I saw a necrosis spot on one photo.....

best of luck.

 

[jtrizzy]

For the record @Bugeye is saying this plant needed more water, if you look in the background you will see the plant behind it has the same issue, they all had this issue as I was watering them all the same. Do any of you think these plants needed more water? Notice the soil and how wet it is, FFOF no perlte added to these other than what comes in FFOF.

That plant that needed more water was in post #13. The plant you are showing is the one you said that had root rot. I have no idea why you are even pinging me if you aren't going to read my responses.

May I hear how root rot happens in your opinion? You clearly have experience, so I would love to hear your opinion on why root rot happens if over watering isn't real.

I just read the essay you wrote and saying this " If providing too much water to a marijuana plant is harmful, hydroponics would simply not work." is insanity. You know oxygen is added to the water in hydroponics. Knowing that, how can you say a plant that is drowning in soil is not over watered when there is ZERO supplemental oxygen like hydro?....Whether the soil is structured or not is irrelevant, it is still over watered. Even if you say you watered too much for the soil structure, it is still over watered. When a plant is watered more than it can uptake constantly, it will be over watered. You simply cannot bring hydro into the conversation as you are comparing apples to oranges. This is why COCO is harder to over water, as it is more aerated naturally, especially when you add perlite in comparison to soil. However you CAN still over water coco. Coco with perlite seems to be the greatest thing since sliced bread on this forum, and there is a reason for that, but it is not fool proof when it comes to over watering. Over watered means there is too much moisture thus cutting off the oxygen the roots need as they are sitting in over saturated medium....of course if you add supplemental oxygen things will obviously be different.

May I also hear what you think is a good soil structure that we all should be using?

I already answered your second question but you refused to read the answer. Happy to answer your other questions but what is the point if you don't read responses? Seriously, are you trolling me now?

I am not trolling you. I am asking a question because I do not follow your logic. So, you are saying a perfectly aerated soil with perfect structure cannot be over watered. Can you share what you use for soil/medium? If it cannot be over watered I am sure many including myself would love to hear it.
