    Hi I am using the alga grow basic nutrients.

    Shake well before use. Add a maximum of 4 ml Alga Grow per 1 litre of water (1:250). Use this solution each time the plants are irrigated during the growth phase. After dissolving in water stable for up to 24 hours.

    My plant is developing a strange color on the leaves.
    the photos are attacched.
    Do someone knows what is happening?

    thanks guys

    I irrigate the plant each 2 days. or when the soil is dry.

    I dont know anything about your fertilizer.

    But the leaves are showing Calcium Deficiency.

    Not sure if it is being caused by lack of Calcium, or your ph is off.
