yellowing/whiting on leaves

[peez]

Have you checked closely for Thrips... 'You can tell when you have thrips by taking a look at your leaves, the leaves will look as if there chlorophyll have been ripped right off the plant. Plants that are damaged can’t be healed thus making it harder for the plant to absorb light.' - https://www.autoflower.org/f74/self-diagnose-your-plants-basic-deficiencies-list-11.html

Hopefully I'm wrong and it is a nute related issue!
