Hello everyone,

I am worried about my avocado plants. They have these problems:

• Their leaves are turning brown (in patches on the leaf blade and continuous on the leaf margin);
• They are gradually losing leaves from below (which makes me think of an event associated with senescence rather than a disease).

As you can see in the pictures I posted, plants are in a plastic pot one with a plant saucer and one without.

CONDITION

Home Temperature: 18°C-20°C.

Light: They have all the light possible (but I live in the Nederlands).

They also receive led agro 7W

Substrate: Coconut fiber and perlite

Watering: ones/twice a week

QUESTIONS AND DOUBTS

- Should I consider fertilizing them?

- Do you think we have fungi to fight?

Thank you in advance for your time 🍃
