ILGM Godfather OG DWC scrog

Weird week this week. I went out of town for 5 days and two lowest leaves were almost completely brown and crispy. I also noticed that my PH is dropping day to day. I clipped the dead leaves and cleaned the res and filled with new nutes. We will see what happens. I did notice that a couple roots are poking through the net pot. I think explosive veg growth is going to happen shortly.
