First DWC Grow Chem Pie 1

This week was a little tough because my ph pen crapped out on me for about a week till i found a hydro store near by. I felt like she was giving me a problem with ph or a deficiency when her leaves started to droop and get slightly discolored. I decided to do a complete flush and restart with fresh rain water added some soluble 16-32-16 fertilizer and hydroguard.. Some roots were begining to not look so good so i clipped the bad ones off earlier in the week, she bounced back fantastic! looking way better than where she was. I never fimmed before but some leaves are coming out weird i guess its normal to see that for the next couple weeks, idk
