Auto fem/ yellow spots

[Siomha]

Hi guys,

I am growing auto fems right now and have a problem with yellow spots on the leaves.

Can you tell me what the plants missing when this problem shows up?
every answer is appreciated!

there is a lot that can cause it. bugs, lack of nutrients etc. whats your soil mix? what lights? feeding schedule? any bug problems? where are you growing them?
