About a month in, things look generally good but I noticed some spots and a few curved leaves. This is Original Moby Dick Auto in coco, I've been adding nutrients as prescribed and adjusted the pH.
My guess, is your pH is screwy. It's fluctuating around which the plants don't like. Consistency is key. pH adjust your water and nutrient solutions, ALWAYS. 6.2 pH is my jam. If beneficials i do 6.3 pH but without, always 6.2
Check your pH meter. Calibrate it if necessary.
