This is my first grow attempt and am growing in my garage. I am growing two plants, a Candy Cane and Jack Herer both auto fems, each in 3 gal. pots. The mix I have is a bottom layer of perlite and Shultz seed starter plus mixed with a 50% ratio of perlite. I topped with a layer of House Garden Organic starter mixed with 10% perlite. Neither are pre fertilized.
The Jack Herer popped the soil a week ago and the Candy Cane a day or two later. They are under 42w cfl's, 3 6500k and one 2700k. Right now they are about 3" above the plants. I just set up two 42w 6500ks as side lights yesterday. They are about 5 inches away from the Jack.
I have a fan blowing on both the plants and the temp above the plants fluctuates between 80-85 F. I have the lights and fan on a 20/4 cycle. The humidity is 45%.
I have been watering with a mix of 50/50 RO water and well water no nutes. I've been checking for moisture using the finger method and when dry watering around the circumference of the plant to just damp. PH of water between 6.0 and 6.2.
I noticed this morning that there was a slight yellow discoloration on the Jack's first set of leaves. Would it be a lack of nutes? I have read that you shouldn't feed until the cotyledon leaves fall off so I have been holding back.
Any help would be appreciated.
