Can't get a handle on my one plant

My one plant had had a recent issue the past week or two and i can not solve it. Last night i fed cal mag, fox farms big bloom, grow big and tiger bloom. Check the ph (6.4) of the feed as well as ppm (543). I teated the runoff and got a ph of 6.2 and ppm of 1540. This is how they look tonight. I don’t know what the issue could be. Temp remains 70-75 and humidity 60-75. I keep the mars hydro at about 75% of its full spectrum right now and the distance is enough to not be light burn. Any recommendations on how to move forward?
