DWC First Indoor Grow

Day 8- Reservior change. System held 9 gallons this time. Week 2 nutrients added. 68ml a & b & 34ml b-52, voodoo juice, piranha, tarantula, & & bud candy. Week 2 also adds rhino skin and sensizym, 34ml of them were added as well. I have been doing research on dwc growing and discovered calcium and magnesium (cal-mag) is crucial when growing using hydroponics. It's a macro nutrient usually absorbed from soil. Hydroponic plants depend on nutrients supplied to them. Cal-mag should be added every reservoir change using reverse osmosis water, because the process removes all minerals from the water. So, I added Advanced Nutrients Cal-Mag to my supplimental nutrients and will use the same amount as the others when doing reservior changes. So, 49ml of cal-mag went in as well. pH is 6.2 and ppm is 900. Day 9- ppm 669 ph 6. Plants look good and healthy. Day 10- ph is 6.5 and ppm is 450. 2 plants are taller than the other 2. I guess it's due to proximity to light. All plants are bushy with tight nodes. Very healthy. Day 13- Plants are growing inches daily, are wide, and extremely healthy Day 14- Plants are growing at least an inch per day. Roots are bright white long and healthy. They look like bleach blonde hair. Recovery from topping is quick. Only about 2 more weeks in veg depending on how tall plants get. Temperature has been very good and stable due to clip on fans, but especially due to Honeywell circulation fan and squirrel fan where tent exhaust. It exhaust in the closet right beside the tent in the same room. We plan on adding duct across closet into a damper that will empty into the laundry room. I think this will help with temperatures in the coming months and increase growth because plants will get more fresh air, rather than recirculating the same air in the room.
