Have A Plant Problem? Check Here First

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

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

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!

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.

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 ?
