what is this?

what is wrong with the lil lady please help

light burn, and those dying leaves are probably the ones you kept from clone and die off anyways. check pH to be safe though.

this is not a clone and i am not using any nutes i knew about the light burn that was from about 4 days ago but today the bottom few leaves have turned yellow i am how ever using the shitty mg autofeed soil i know that is prob one right? but is this caused from over under watering the ph in my tap water than i am using is good as well.
