Cannabis plants are resilient. The plant grows successfully all over the globe in many different climates—it’s called “weed” for a reason.
What’s wrong with my weed plant?
This is a bad idea and will quickly lead to nutrient lockout or other nutrient deficiencies. Nutrient lockout occurs when a weed plant can’t take in any more nutrients.
Overwatering cannabis plants
Here are some common mistakes newbie weed growers make.
Overwatering is a common occurrence with new growers, excessive watering inhibits oxygen from reaching the roots and can result in the drowning of your plant.
You can end up damaging your cannabis with low-stress training techniques as well as with high-stress training techniques, although it may be easier to damage your plant with HST because it literally consists of mutilating your cannabis plant.
This happens because most high-intensity lights have to be used in combination with higher CO2 levels so your plant can absorb the light properly, if the CO2 level is too low your plant can get stressed and show heat stress signs, resulting in slow growth.
When this happens, your plant will start to show different symptoms that can confuse you, when you see your plant getting much wider than the pot you should start thinking about transplanting it, failing to give the roots the space they need to grow will result in droopy leaves and other signs associated with overwatering of nutrient deficiencies.
These numbers are just a guideline, you should always look for the signs your plants give you and adjust the environment accordingly.
How to deal with it
Plants need nutrients to grow, depending on the medium you’re growing in, you’ll need to not only provide all the macronutrients but also a good amount of micronutrients.
You can also spray your cannabis with a mix of water and a small dose of organic insecticide to prevent them although this is not recommended, insecticides should only be used when you already have bugs and are used to eliminate and not to prevent them.
Choose a strain for your region or microclimate. Some strains do better in some climates than others, and strain genetics will have a big impact on the growing season. In the northern half of the US where the season is cooler and shorter, growers might want to grow indica-dominant strains, whereas sativas will do well in the more hot and humid southern states that have longer growing seasons. Type of soil, volume of rain, and abundance of sun versus shade are other microclimate variables in your microclimate to consider when choosing a strain.
Let’s talk about what “weed season” means in the US, and how you can time your outdoor grow to get the best results.
Harvesting happens when the plant’s flowers have fattened up but before the very cold weather comes on, typically by mid to late fall.

Mid-to-late fall: harvest season
A photoperiod plant will continue to live its best vegetative life until the light-to-dark ratio starts to tip in favor of darkness. When photoperiod plants start getting 12 hours of darkness, they will move into their final phase — and perhaps the most exciting for growers — the flowering stage.
During this phase, growers might consider topping and training their plants to encourage outward growth. This provides more even distribution of light to the leaves while also managing overall plant height. More water will be needed as the plant develops large root systems and additional nutrients like nitrogen are beneficial as the plant matures.
Are you thinking about growing your own cannabis? New to being a plant parent? Wondering when you should plant your cannabis seedlings outdoors?
In the Northern Hemisphere weed growing season can kick off as early as April, when gardeners and farmers might start seedlings indoors. Cannabis plants typically flower in late summer through fall, and the season can run as late as mid-November in warmer climates where some cultivars take a long and luxurious time maturing their buds.
There are also cannabis plants that aren’t light-sensitive, called autoflower varieties, that will automatically flower on their own at a particular point of their maturity independent of how much light they’re getting. These plants tend to have much shorter life cycles, which is appealing to some gardeners.
