White Crack (Mephisto Genetics)

8day - I'm transplanted White Crack to 6L airpots and move it to vegbox; 10day - I found some yellow spots at the edge of the leaves, looks like to much nutrients for the start, so I decrease TDS in the tank to 550ppm and PH to 5.7, at current moment there is one watering at the evening; 12day - after 2 days when I found yellow spots, plant feels much better and looks healthy;
