Fungus infections are a bit different than clogged pipes.
I'll be honest I have no idea what would cause those issues
Fusarium fungus colonizes the xylematic tissues of plants, blocking the vessels. This blockage causes
yellowing and wilting of leaves and stems, together with necrosis and, in severe cases, death of the host plant.
Symptoms of Fusarium
- Rotting at the base of the stem
- Lignificación of the stem
- Nutritional deficiencies on the leaves, which turn yellow and necrotic but remain attached to the plant
- Only one branch (or part of the plant) can be infected
- Root rot
- If we cut the stem, we observe brown vascular bundles
- Normally, the infection advances from the lower part of the plant toward the top
Fusarium penetrates from the soil through wounds in the roots or the stem and via the root hairs or the younger epidermal root cells. It reaches the
woody tissues (xylem) where it develops, preventing the transmission of water and spreading to all parts of the plant.
Unfortunately, there is no effective
treatment or
fungicide to combat Fusarium or treat infected plants.
Prevention is, therefore, the best and only option we have to avoid it; we should be very strict with
hygiene in our crop, disinfecting the trimmers, irrigation tanks, plant pots, etc. before their use. Needless to say, using a quality substrate with known properties is very important.
We can also water our plants less often and ensure to keep our substrate under 30ºC. Another commonly used option by many marijuana growers is adding
Trichoderma to the growing media, a beneficial fungus that – in addition to providing an explosive growth of the roots – colonizes the soil and prevents the growth of other fungi.
