Short info to my grow: Growing some feminized (Northern Lights, Somango) and some Autos, the problem doesn't show on all strains/plants, some look perfectly fine without the dots. I am growing in soil, and as nutes I am using "PlantMagic Organic Oldtimer", currently watering maybe once a week.
This is not my first grow so I am "somewhat" experienced. I know spider mites, I had them last year. This are no spider mites. I checked the undersides of the plants, there are no mites. I even checked with a loupe.
The problem seemed to have gradually developed once I switched from my old MarsHydro 300W lights to my new fixture which is 4x CREE CXB3590 lights. The light is currently about 35-40cm (13-14inch) from plants. Light bleach?? I am a total loss!
Please see the pictures. You can't "rub off" the dots. You see some leaves where there are more dots in the middle. Some leaves are starting to get yellow and some also have brown spots. I am baffled since my grow otherwise since I have the new light is great. I am just puzzled because of those spots.
(I DO have a fungus gnats problem but I always had them, remedy for them is already on the way in the mail).
Thanks for any help!
