Any idea what this could be?

I'm going on the 2 week of flowering... organic soil, organic nutes.

RO water.

Potassium will cause dots like that. Although I do not see much leaf tips browned as the earlier stages caused during the potassium def. During late stages of potassium def. you will see both leaf tips browning followed by leaves yellowing and brown dots.

I'm be leaning more towards a manganese deficiency on this one.

I think it is an mn def. This will start with dots then do the leaf tips then turn yellow and fall off.
