Common weed growing problems

Catching and solving problems quickly means bigger, bulkier, more potent buds. Your cannabis plants will love you for it!

Step 1: Verify Watering Habits & Root Health

When the air feels moist or humid (or a humidity monitor alerts you to high humidity), it’s extra important to ensure that plants get plenty of air circulation and have lots of air movement. You also want to avoid letting leaves touch each other during periods of high humidity. You can fix constantly too-humid conditions with an exhaust system, fans, and possibly a dehumidifier.

If plants are very leafy and leaves are laying on top of each other, it dramatically increases the humidity of the grow space. In this case, removing leaves (defoliation) can help. Try to remove leaves that are in the lower/middle part of the plant, leaves that are covering bud sites, and leaves that are touching each other making wet spots.

Even if other factors can be confidently ruled out, it is still possible that it’s not the nutrients themselves that are the cause of the issue. It’s quite possible that the cultivator is feeding their plants the right amount of nutrients yet the marijuana plants are not absorbing them properly due to one or more reasons.

Epsom salt is particularly useful because it also includes sulfur and helps cultivators fight off sulfur deficiencies. Sulfur deficiencies can occur during the vegetative phase and the flowering phase, and can be hard to differentiate from a magnesium or nitrogen deficiency.

Nutrient Uptake

When a cannabis plant is fed, the plant’s roots absorb nutrients from the moisture and grow medium, or in cases of hydroponics, the water that the roots are suspended in. In layman’s terms, the roots eat the nutrients and get them to where they need to go throughout the plant via a process known as nutrient uptake.

Common Nutrient Deficiencies During The Vegetative Stage

In addition to the previously mentioned types of nutrient deficiencies, which can all occur during the flowering phase, several other types of nutrient deficiencies are common during the flowering phase. When a cannabis plant is flowering it requires more nutrients, which is why so many more types of nutrient deficiencies occur during this phase of the plant’s growth cycle.
