Crown Royale DWC grow

This week she grew a lot. Nice flat plant with tons of bud coming on. I been working a lot on her training and have her about they way I wanted. This is turning out to be my best grow yet. One of the problems I ran into this week was with the cooler pump. It had a short in it and I was getting shocked from it. Rewired the temp controller thinking that was it but in the end changed the pump out. Also not trusting my PH meter. Have some powder coming so I can calibrate it. Upped my solution temp a little to 69. From all I been reading that sounds like optimal. With my poor man cooler, I been using frozen coke bottles and swapping them out every 12 hours. Seems to be working well but I am looking into a peltier cooling rig and keep the water chilled in the cooler and not have to do bottles anymore. 3 full weeks in flowering, 6 more to go :)
