This is my first grow I am 3 days into my 3rd week of growing, I am using DWC a double outlet air pump a six inch bouble stone in each, in a closet 3ftX5ft, two plants each in a 5gallon bucket with net pot built into the lid, a fan blowing. I am using Flora Nova, I am usign 3 gallons of water per bucket with 1tsp of nutes in each bucket, water out of the faucet ppm is 0.30 after I add the nutes it goes to 0.70, I am using 4 T5 bulbs 4ft long, I use the color scale with drops to test my ph, which is at 6.0, I started using Sure2Grow cubes, surounded in hydroton which was rinsed out befor being used. The strain is unknown.

My leaves are turning yellow I believe it might be a lack of calcium, which I am going to go buy some Cal-Mag. The pics are of both plants.

What does any one think, and if I am right how much do I use. I an not a veteran so if I am wrong please steer me in the right direction.

Thanks.
