Does anyone reconise this? It only occurs on one of three plants and only on a few leaves. I removed it, it has not appeared again, though I would like to know what caused it. I fertelise weekly, only 1/4 of the recommended dosage. Mr C
it looks like fert that has touched the leaves while your feeding, or a residue from the water your using......Peace out....Sid
Thanks for the valuable inputs. As for checking underneath the leaves, I did not notice anything when I removed the affected leaves. The problem has not occured again which gives me the idea that I might have spilled some fert on the affected leaves. I use a solution "NITROSOL" that has to be diluted with water. Guess I have to be more "carefull" when watering with this stuff.
