Hot soil can cause your plants to become dehydrated and struggle for survival. If you notice your plants are wilting or changing color, your substrate might be part of the issue. Heat stress can limit your plants’ ability to grow and develop, which might even cause their death.

Hot soil is a phrase that gets thrown around a lot in the
cannabis community, but what does it mean? It does not refer to the temperature or the visual beauty of your medium. Instead, hot soil references an excess of nutrients and additives. This excess can create a
range of different problems with your crop. Unfortunately, hot soil is a very common problem that beginners run into. So, let’s learn why soil can easily become hot and how you can fix it!

What is hot soil?
Hot soil refers to soil that is overly amended or fertilized, causing a variety of issues in one’s garden. Many beginners run into this problem because they are overzealous and end up giving their plants more
fertilizer than they can metabolize; this phenomenon is also called “
nutrient or ‘nute’ burn.” This can be caused by over-amending soil or feeding liquid fertilizers at too high of a concentration. You won’t be able to tell if the soil is hot by looking at it or feeling it, you will have to read
your plants and look for symptoms that indicate the soil is too enriched for them.

What happens to cannabis plants when they’re overfed?
Cannabis plants will show signs of being overfed rather fast. Tip burn is the first sign that
the medium is too hot for them. This visual symptom displays on the tips of the plant’s leaves. The
tips will turn a yellow or brown color depending on the severity.

Another symptom of hot soil is seeing signs of
nutrient deficiencies in your plants. It might seem counterintuitive that soil with too many nutrients will cause nutrient deficiencies, but it’s possible due to lockout. When there is too much of a certain nutrient, it prevents your plants from metabolizing other nutrients. An example of this would be an excess of calcium causing phosphorus-like deficiencies such as purpling of stems and yellow and
brown spots on leaves.
There are many signs that your soil is too hot, and recognizing them is important. However, knowing how to fix it is equally as important.
How to fix hot soil
Fixing hot soil is relatively easy and should be done as soon as possible to prevent further damage to your plants. The easiest option is to water your plants heavily to wash the excess nutrients out of your medium. You should water till a large amount of runoff has bled out the bottom of your pot. Doing this type of flush weekly can help prevent the possibility of your soil becoming too hot, especially if you are using salt-based fertilizer.
If
flushing with straight water isn’t solving the issue, try using different products that can aid in flushing the nutrients out. A simple product every grower should have is some kind of
yucca extract.
Yucca will make your water “wetter” to flush your medium out more efficiently and add other beneficial hormones to your plants.
Products containing enzymes will also help make your soil less hot because they will help break down nutrients and allow them to be flushed out of the medium. A more severe case of hot soil may require a more serious product, such as hypochlorous acid, to remove the excess nutrients.

The best strategy to fix hot soil is being proactive and taking steps to prevent your soil from becoming too hot. Weekly flushes with plain water are a good insurance policy to prevent excess nutrients from building up. If you are using bottled nutrients, especially salt-based, use only the lowest recommended dilution rates at first to see how your plants respond. After that, slowly increase the concentration till you find the sweet spot.
I think some are even sold using that lie as a selling point.
