Weed growing problems

However, usually you can tell when plants have bugs because you see the bugs themselves, or it actually looks like bites on the leaves.

More light = More yields + Faster Growth (up to a point)

Cannabis loves light! But not too much…

Overwatering is often difficult to diagnose because it can cause a surprising number of symptoms

Step 5: Diagnose Pests (sometimes you never actually see the bugs)

If you want to cut through the technical marketing talk and get straight to what works, it’s important you learn a little bit about what kind of nutrients are needed by the cannabis plant during different stages of growth. These days, there are lots of nutrient systems available that are specifically formulated for plants like cannabis, and they help take all the guesswork out and give your plants exactly the nutrients they need. It doesn’t have to be expensive to provide everything you cannabis plant needs! Learn everything you need to know about cannabis-friendly nutrients.

Younger plants usually are fine with high humidity, but humidity is especially dangerous in the flowering stage because the insides of the buds can grow mold and still look fine from the outside at first.

Step 4: Identify Light Issues

What to Do: The goal is to give your plant exactly the kind of nutrients it needs to thrive, and provide the correct pH at the roots so your plants can properly absorb nutrients.

With the right tools, the task of maintaining humidity can be close to automated, and you will see huge benefits compared to the amount of time and money you invest.

In order to kill the mildew, it is best to mist it with a mildew eliminating spray. Also, lowering humidity and increasing airflow in the grow room is enough to stop it from coming back.

Don’t freak out if something does start to happen to one of your plants, as it’s not the end! The best course of action is to view the signs and symptoms on your plant and then compare them to the symptoms listed below. Once you find the right match, continue your research and follow the instructions for how to cure it and within a few days you should see signs of recovery!

When you are overwatering the plant, it will cause the leaves to curl downwards and they will seem very rigid in tight because they are so full of water. Growth will also slow down tremendously and if you don’t fix it quickly, it can lead to root rot.

The burning always starts at the very tip of the leaves, so look out for that subtle clue. If your plant begins to show signs of burn, hold off on feeding nutrients for a week or two and then you can resume. This will allow the plant to flush out the high quantity of nutes.

Luckily, cannabis plants are extremely resilient and can withstand a harsh environment or an invader for some time. This is convenient because it gives you time to figure out what the issue is and treat it before your plant is completely ruined.

Also remember that with most of the nutrient deficiency and leaf problems, the issue is pH levels. So always be sure to check that first before trying to increase any particular nutrient.

Whenever the tops of your plants are too close to the grow lights above, it will cause the leaves to yellow and burn. The easiest way to spot this problem is to look out for the leaves that are closest to the light; they will begin turning yellow first and then it will spread to other areas to the plant.

Under Watering & Over Watering

Another issue caused by high humidity and low airflow is bud rot. Overwatering can also cause this to happen, and essentially the results are the rotting of your cannabis buds. It will start from the inside and will slowly turn them brown and moldy until the whole bud is ruined.

Nitrogen toxicity, on the other hand, is caused by feeding too much nitrogen to your plants and is often referred to as "The Claw." This is because one of the symptoms is the ends of your leaves will curl or claw downwards. They will also turn dark green, which is another sign of N toxicity. To fix this issue, just lighten up on the amount of nitrogen mixed into the nutrient feedings.
