I won't be able to spray it with any fungicides at the moment because I don't have any. I'll have to buy several pest treatment products soon.
I don't think the orange powder is any of my fertilizer because nothing I use is that colour and I try to never get water into those areas. I would think it contains iron or fungal spores. Maybe from its previous owner? I won't be fertilizing my paph armeniacum soon.
Anyways I just bought new fertilizer that contains 10.49% nitrate (NO3) and 9.41% ammoniacal nitrogen. No urea. ...The nitrate worries me a little on my other paphs. I bought it because these nitrogen compounds were supposed to be faster acting than urea on orchid media. How does nitrate kill a Paph?
