If you're asking about the yellowish patches and little brown dots on the leaves, that's pretty normal. your plant's flushing various nutrients and wastes out through those big leaves to go through flower phases. prune that shit. sometimes little discoloration speckles like that happen just from the way droplets of moisture refract/focus light...like tiny magnifying glasses burning little areas kinda brown. 'Course, that's just my assumption, based on looking at one photo and my own experience with plants, but it looks like your plant's okay. Hope so, and good luck with it.
