Revelry,
Hello and Welcome to The Garden Helper's Forum??
I am not a expert on those
plants but could I ask some questions about how you are
growing them,
and that way it may help a bit in knowing what it is. I took a quick peak at your Pelargonium Page,
are you strickly
growing them in the peat pots???
Could be a combination of things, I'd say the dirt for the first one, and sounds like a touch of rust maybe??? Or nutrient deficency?????
How are your watering practices???
And are they all indoors or outside???
Are they still in the peatpots or out in another
growing medium???
