Fingers - Fast Buds Stardawg

You notice how the leaves are yellowing from the tip to the base and develop rust spots? that's a textbook potassium (K) deficiency; I can't see it, but there might be dark / metallic blue patches too, then you also have phosphorous deficiency. Anyway, what you need is to up the flowering nute or PK booster, what the plant uses to make buds.
