Re: deformed growth
Simone was wondering about a calcium or boron deficiency.
You could test your tap water for hardness or phone up
your water authority for a breakdown. If you have enough
calcium which seems likely, try adding a little boron in
the form of boric acid., H3BO3, maybe a fifth as much by
weight as iron.
