Looks like Nute burn..... what ppm are you feeding the little thing, at the stage of growth your plant is, I would say you should be no higher that 400 ppm

right at 400, I was thinking nute burn, I went 50% on the nutes the first week and now its time for a reservoir change. Should I go 50% Again?

I would clean it up, that is, cut off the worst of the yellow leaves, and trim the bottom leaves (helps with bug control also), and leave it at 400 for a couple of weeks, and then slowly raise it, keeping it around 600 in Veg.

Once in flowering, I try to keep the nute level at 600 to 800 for the first week or so, and then slowly raise it to around 1200 till its time to flush
