DWC First Indoor Grow

Plants started week in individual5 gallon buckets because recirculating dwc system wasn't finished yet. It consisted of 5, 3.5 gallon buckets. 4 for plants and one as a reservior. Each bucket with a plant had a 4 inch ceramic air stone. All 4 air stones were supplied by a hydrofarm air pump. I'm not sure the wattage. Day 1- Transplanted seedling from solo cups of coco courses to 6 inch net pots filled with grow stones. Rinsed coco from roots with water to remove coco from roots. Then stabilized grodan and filled with rocks. I had rinsed rocks well and soaked them in 5.5 pH reverse osmosis water for 24 hours. The plants then went in 5 gallon buckets with 4 gallons of RO water pH to 5.7, didn't add any nutrients. Day 2- pH jumped to 7.2. Added Advanced Nutrients master grow recipe. 15ml a & b and 7.5 b-52, bud candy, voodoo juice, piranha, & tarantula. Put frozen bottles of water in buckets to keep solution cool. Plants look awesome. Day 3- Recirculating system ready. Consists of 5, 3 1/2 gallon buckets. 4 for plants and one for a reservior. Takes 13 gallons of water. Filled with water and nutrients and moved plants. Day 4- plants are looking beautiful. Adjusted pH from 7.2 and added 1/2 strength nutrients due to lowered ppm. Day 5- ppm 491 and pH 6.2. Added 3/8 strength nutrients. Topped for the first time. Day 6- Topped plants. Day 7- ph adjusted from 6.9. Ppm 900
