This is like day 9 after flipping lights. DWC. One looks great no issues other than a few leaves looking rusty on outer edge. Now my strawnana very sativa looking and skinny the lower leaves are yellowing and the veins are dark green. So I thought calmag. Dropped 6ml two days ago.

This girl has continually dropped ph into low 5s. Yesterday I set it to 6.1 it's at 5.7 already. I tried giving more food but didn't do anything. I thought maybe I was underfeeding. I did a res change and same problem.

Any ideas?
