Need help identifying my leaf problem!! ASAP PLEASE

[newfarme]

The plants are about a month n half old into veg. But only one plant has this problem out of the three. I'm using CFL's and soil medium to grow. The problem seems to have started from the bottom leaves and making they're way up. What could this be and how can i fix it? Thank you!

 

[Clonex]

I dont use your setup so cant help but may i ask whats going on with the green pot ?

 

[Cooter@666]

Looks kinda like a calcium def,...a few table spoons of Dolomite scratched into the soil should correct the issue, i'd also give it a foilar feed with Epsom Salt...Hoestly they look really healthy

 

[newfarme]

It was a plant my friend tried for the first time and didn't go that well so he gave it to me.

 

[jpill]

whatever it is, its starting from on the bottom, thats a sign right there. cal-mag may be off or ph is off. not really sure unless its old damage.

 

[newfarme]

I have a Ph meter but i bought it from ebay. You think it will be accurate enough? and how do i add cal-mag into the soil?

 

[VanishingToaster]

looks like pH to me, splodging from the bottom up is a big indicator (mine did that lol) u can stick ur meter in the soil gently to get a reading.

 

[uhavealighter?]

ITS NOT A CALCIUM DEFICIENCY. It either a ph problem or magnesium deficiency. But you do use epsom salt. Its magnesium sulfate. HAHA. Cooter had a bad diagnoses, but good cure.

 

[newfarme]

My pH is showing 7.0 is that good or bad? how much epsom salt do i add for this n how long will it take for it to take effect?

 

[imlovnit24/7]

Since the older growth being affected I say its Mag def, tho that could be due to your soil having a ph of 7 and you're having ph lockout. Most plants in the world prefer more acidic soils averaging between 6-6.5 aside from getting ph adjuster from the hydro shops I reccomend adding maybe 1/4 of soil sulfur. A cheap and short lasting fix you can always use anywhere from 1-5 TBSP of white vinegar.

After you get that back down to a suitable ph the lockout could fix itself and might not have to give it any Mag

I may be wrong, but my 2 cents: Try removing the effected leaves and treating the plants with a good quality fungaside like Seranade. I had a similar situation and treating it as a nute or enviromental problem had no effect on the symptoms, and my plants just kept getting worse. If You got that one from a friend, then that is probebly the cause, as your other plants show no signs and they all share the same enviroment. I find I have to treat on a regular basis to keep this particular nastiness away.

If left untreated it will infect your other plants, and if it doesn't kill them, it will lead to a very low yeild, as it progresses up the plant and eventually to your buds.

I may be wrong, its been known to happen.

What??? You clearly have no idea what you're talking about.

Pictured is a White Rhino that I have, showing the early signs of an infestaion. This is NOT a deficiancy, lockout or bug. Its a fungas and responds to a fungaside ( Seranade ). I have been batteling this scourge for over a year, thinking that it is some kind of nute problem, soil problem, lighting problem or temp problem. It was none of these things. I lost an entire crop due to my thinking it was on of these other issues. Until I started treating with an anti fugas preparation, I was having absolutely NO positive results. Believe me, I tried everything in the book, from flushing the soil, to cal/mag in my feeding schedule, literally everything but recognizing it for what it was. Now I treat with a fungaside on a WEEKLY basis, religiously, and it has cleared it up to a managable leval. ( I don't think it can be completely eradicated outside of a complelely new enviroment, new plants, new everything), but it can be managed. My grow proves this out.

Pictured is another white rhino with the leaf problem. This is a MOLD or a FUNGAS. Not a nute or enviromental issue.

I'm looking at these on a 42 inch screen in 1080P and your photos look nothing like what is happening in OPs photo.

What is shown in my picts is what happened overnight, this is the problem in its infancy. I may be wrong, but I figure $20.00 spent on a bottle of seranade is very cheap insurance. What if he takes everybodys advice and treats it as an enviromental issue or nute issue and the problem persists? Or gets worse? When a simple anti fungas regime might be the trick to clearing this up. I'm certainly no expert and never will lay claim to that title, I'm just relaying what worked for me in the hopes that others may be helped.

My point is, don't give people info and present it as fact if you do not know it to be fact. I agree, preventive maintenance is a wonderful idea but you claimed it to be fact that OPs problem was the same as yours. One thing about giving advice to someone else growing cannabis, you better damn well be sure you're correct and if you are not 100% absolutely positively certain, say so. Present your opinion but make it known you don't know it to be fact but it's what you are thinking it may be. People screw up other peoples entire grows all the time from presenting their opinion as fact when the truth is they really have no clue what the hell they are doing themselves.

Nothing personal, I'm just saying. Mistakes like this could cost someone months of work and thousands of dollars.

1) I am not saying that this is definately his problem, Im simply saying that he should take it into consideration as a possible sourse of his problem.
2) I'm not saying that this is the ONLY treatment to give his plants. Obviously he should be considering all of the possible causes of what is happening to his plants, and correcting the various variables such as nutriants, lighting, heat etc.
3) How is anyone going to be "damn sure that you are correct" or "100% correct" without actually being in his grow room. If you think you are that good than more power to you, I know I never will be "100% correct" or even "Damn sure" in this kind of scenario. But if you are not willing to take into consideration ALL of the possible vaiables and causes then I don't see how you can ever be a successful grower with that kind of attitude. I am not trying to toot my own horn, just offering up a possibility that may have been missed.
4) Again I am just posing this as just 1 of a number of possible causes, I am not trying to put this out as THE cause. It is just a suggestion, nothing more, nothing less. Take it or leave it.

i'd get ur pH down to the 6-6.5 range give it a couple days and pay attention to new growth and any areas that are non affected. it may continue to leech through onto current leaves but if it starts appearing on new growth, then we might have to look at other options.

your plants will be fine for an extra day or two if u need to make a decision, not many things gonna kill em or do serious damage in the short term. whatever you do, dont rush ahead with any advice, better to have a correct diagnosis. the mouldy dudes pics do look different to yours, wouldn't worry too much about it, whats ur humidity ?

 

[MrGhettoGrower]

Yo dawg you got all these growers one saying this or another one saying that
it not that hard. I would ask what dirt and nutes are you using or plan to
use. The plant looks more like the ph issues or it may need to be fed looking a little
flat the leaves. As for your ph meter it all depends on which one you got.
You did get calibration fluid to calibrate it?
