Plant leaf spots and yellowing, help!!

I noticed the tips of some leaves getting yellow as well as some brown spots. Only a few of the leaves are affected. Could it be light burn? Or is it a nutrient deficiency, Ph, etc. (I changed my light last week to a ViparSpectra P1000 LED from a 600w philzon LED.)

I don’t think it’s a deficiency, I think it’s the beginnings of burn. Same thing happen to my plants. Scale back the nutes.
