Rolls...does that look like those mites that poison the plant...broad mites. Look them up.

I have never had them, but that was all I could think of.

(the second photo reminds me of when I FIM a top kinda)

If it is BM, then all apologies....I hear that they are about the worst.
Thanks for replying man, I will try a few things and post back if I am able to fix it (so anyone else with this problem will know)

Cheers

Duck that is nute poisoning of some sort, if I had to guess....hard to be sure....

Flush it and then let it grow dry....see how it responds.

P.S. Do that Rolls....we all benefit from sharing. Good luck!

Below are a list of Marijuana Plant Problems And Pics To Help Diagnos Said Problems.. I Just Thought This Would Be Very Helpful To Anyone Experiencing Any Problem For The First Time And Are Having A Hard Time Diagnosing There Plants Problem...





Heat Stress

Look closely, and you'll see the brown leaf edges that are indicative of heat stress. This damage looks alot like nutrient burn, except it occurs only at the tops of the plants closest to the lamps. There's only one cure for this...get the heat away from the plants, either by moving the lamps or moving the plants.



Figure
Nutrient Solution Burn

There's a good chance that this bud was subjected to nutrient solution burn. These symptoms are seen when the EC concentration of hydroponic solutions is too high. These symptoms also appear when strong nutrient solution is splashed onto the leaves under hot HID lamps, causing the leaves to burn under the solution.

Figure
Many hydroponic gardeners see this problem. It's the beginning of nutriet burn. It indicates that the plants have all the nutrients they can possibly use, and there's a slight excess. Back off the concentration of the nutrient solution just a touch, and the problem should disappear. Note that if the plants never get any worse than this here, then the plants are probably just fine.

Figure
Figure 4 is definitely an over-fert problem. The high level of nutrients accumulates in the leaves and causes them to dry out and burn up as shown here. You must flush with clear, clean water immediately to allow the roots to recover, and prevent further damage. The find the cause of the high nutrient levels.

Figure
Over Watering

The plants in Figure 1 were on a continous drip system, where nutrient solution is constantly being pumped into the medium. This tends to keep the entire root system completely saturated. A better way would be to periodically feed the plants, say for 1/2 hour every 2-3 hours. This would give the roots a chance to get needed air to them, and prevent root rot and other problems.
Don't be throw off by the fact that the plants in Figure 2 are sitting in still water, this is actually an H2O2 solution used to try and correct the problem. Adding an airstone to the tub would also help add O2 to the solution.

Figure
pH Fluctuation

Both of these leaves in figure 3 and figure 4 are from the same plant. It could be over fertilization, but more likely it is due to the pH being off. Too high or too low a pH can lock up nutrients in the form of undisolvable salts and compounds, some of which are actually toxic to the plants. What then happens is the grower then tries to supplement the plants diet by adding more fertilizers, throwing off the pH even more and locking up even more nutrients. This type of problem is seen more often in soil mixes, where inconsistent mixing of the medium's components leads to "hot" spots.

Ozone damage

Ozone damage typically found near the generator. Although a rare problem, symptoms generally appear as a Mg deficiency, but the symptoms are localized to immediately around the generator.

NUTRIENT PROBLEMS

Root stunting

Root stunting is characteristic of calcium deficiency, acidity, aluminum toxicity, and copper toxicity. Some species may also show it when boron deficient. The shortened roots become thickened, the laterals become stubby, peg-like, and the whole system often discolours, brown or grey.
Symptoms localized at shoot growing points.

New shoots unopened; young leaves distorted; dead leaf tips; pale green plant copper deficiency
New shoots withered or dead; petiole or stem collapse; shoots stunted; green plant calcium deficiency
Young leaves pale green or yellow; rosetting or dead tip; dieback; l
Hey I have these problems and ot comes from over nut giving them grow during veg stage heavy I just fed them yesterday and found out afterwards can I flush all of that shit out and wait til the next watering to give them the correct amount of nuts
 
These poor babies are 14 weeks veg and 1 week since I threw them under 300w led from t5. My ph was low about 5.5 and last water (3 days ago) i flushed with ph at 5.8. I checked the ph of the RO water and it was really high almost 8.

When i threw them under the led they started to get really droopy and wierd spots.20190213_025228.jpg 20190213_025212.jpg 20190213_025205.jpg 20190213_025201.jpg 20190213_025152.jpg 20190213_025228.jpg 20190213_025212.jpg 20190213_025228.jpg 20190213_025212.jpg 20190213_025205.jpg 20190213_025201.jpg 20190213_025152.jpg

About 2 weeks ago i was out of town and my brother watered them with RO no nutes so im assuming ph was high then.

Is that ph level of ro normal? I checked the ppm to see if maybe i need to change the filters whiich ive had for about 6 months.

Some Hydro-Head will have to come along Ez...sorry.

They do look pale and purple-stemmed....if it were soil/hempy
I would flush and then let them dry out.

Good luck,

Hello, second week of flowering and this happed on my GSC. I was scared it could be an infection and took the leaves off. Mostly worried about the spots, maybe a second opinion would be beneficial, this is only my second grow. Thanks!

Rolls...did you ever figure it out?
JC
Hey JC,
The closest I came to a conclusion was White Fly - There is a ton in the area (citrus tree and another tree ladden with them)
I cleaned them religiously with organic soap every 2 - 3 days and that helped infinitely and then after 3 weeks of that I was exhausted!
Here are some progress pics - "Good looking from far away, far away from good looking" might the sentiment that runs through your mind as you look through the pics haha :P

I was hoping some experienced sativa growers could comment if the thin and cupped nature of these leaves are normal? (see pic "7")

Also hoping that someone could identify what would be causing the detoriation of the leafs? (see pic "9")
I'm suspecting white fly...but then again I suspect white fly is behind the 2009 GFC lol

Cheers,
Rolls :)

Looks a lot like powdery mildew which GSC is prone to. Humidity and Airflow? Get it under control asap before it takes over.

Any idea what's going on? I did some google searches and it said maybe a phosphorus or sulfur deficiency?

Soil grow, 5 gallon pots, pH level at 6.4, my other plants aren't looking quite as bad as this, and I am using the same nutrients (NFTG line)

View attachment 4293003 View attachment 4293004 are those pre male flowers? & my tips are clawing but no signs of yellowing,spots,darkening etc etc.
I don't know much, but I picked out 7 males before they were males... don't ask me how. Just seen a lot of balls in my lifetime I guess, ha. They look suspicious (but don't they all..?) Keep your eyes on them, and will you keep us posted when you find out?

And if the tips curl down at the ends, with a darker green - is that N toxicity? I'm seeing that in flower, which makes sense after all they've been through. But I thought N in veg was a good thing... I didn't even use veg nutrients and they still look like they have/had too much.
Sorry, I wasn't much help. More questions than answers. :oops:

That's what she said.



Lmao, but in all seriousness I thought it might've been wind burn since my fan is pointed slightly @ my canopy. I pointed it upwards now and don't really see a difference(3 days). This one is in a more coco than soil mixture so I'm guessing N deficiency ?

Yep, pretty sure she said that - because who isn't stoned at this time of night/day/afternoon or evening? lol...

So if it was the fan, the leaves would visibly recover? Good to know :)

And how do you tell the difference between a N def or toxicity if they both cause leaves to curl under? :?: What are you going to do about that?

(I also read that my Autos - one has tips looking like yours - could do that to preserve moisture in low humidity; and/or a reaction to the cold, and/or something to do with nutrients. Take your pick. I'm so confused right now.) o_O
