Charlottes Angel Auto DWC

Started my first Deep Water Culture grow a week ago, also first try of Charlotte´s Angel and really curious about this supposedly High CBD and very Low THC strain from Dutch Passion. I have a simple setup you can see in the photos too, a 10L bubble bucket with non hydro-fixed hydrograins so I had to tweek the water a bit since I notice they push the PH a bit upwards. My tap water is also close to Ph 8 so I used Hydrochloric Acid to get it to 5.5 with nutes. Might try a batch of rain water for next water/nute change which is around 5.7. Will also be adding Co2 later, I´m using simple but functioning meters for water temp, Ph, humidity and air temp. The light is a chinese Ebay 100 bucks COB Led light full spectrum that I used on one soil grow before, supposed to be 1500w and unsure about that but bright as hell and definately full spectrum. The soil grown OG Kush loved it. The plant seems ok for now and the first roots just shot out into the bubbly water, fun to see how it will do!
