Hello, can someone help me ID this issue? pH at 5.9, air temp ranges from 72 to 82 F, rez temp ranges from 60-74 F, RH ranges from 44-57% (have to run AC to keep temps down), EC currently at 0.5, plant is a few weeks old. Noticing leaf discoloration and slight curling. Using quantum boards at 15K lux. Any input? Thanks!

Adding some more photos. I've been mostly keeping the pH below 6.0 (noobie here, probably adjusting the pH too many times instead of letting it flux more) and after looking at additional photos i'm seeing yellowing between veins and at least one red stem, which might indicate a magnesium deficiency. I will keep pH in the 6.0-6.5 range for at least a week and observe the new growth.
