I have noticed some black spots appearing on the leaves of an autoflower I am growing and was wondering if anyone could provide some advice as to what might be causing this. They do seem to start off as yellow blemishes and then turn black (clearly as the cells are dying off). Not sure if this is nutrient burn maybe? It is not on all the leaves and they can be found on some newer leaves and and also on the older ones.
Any advice is really appreciated.
