The soil may be low on cal / mag.

Are you adding nutrients yet?

Nice. Hopefully someone with biobizz experience can help.

I'm weak with soil, and no experience with biobizz. :dunce:

If you are growing in soil, and you have hard tap water, then I would be surprised if this is a calcium or magnesium deficiency. Are you sure they aren’t burns from water droplets? Or is it more widespread than it looks in the photos?

Is it cal mag deficiency?
