1 under developed plant and questions.

A buddy of mine is letting me participate in his grow. Actually he is doing all the work and I get to come watch and help a bit. I do a lot of research on the subject because I'm excited about it.

A little background into it. There are 5 total plants in a box roughly 4 1/2 feet tall, 2 1/2 wide and 3 1/2 - 4 foot long. These are estimates, the box is obviously at his home and not mine so I can't measure.
There are 4 23 watt 6500k cfl's, 4 20(ish, margin of error 3)watt 2700k bulbs, one 32 watt 2700k bulb and one 24(margin of error 2) watt 2700k cfl. 3 plants are 3 foot tall and 2 are about 3 1/2 foot tall. The light is spread fairly even. Each plant has at least one dedicated 2700k and 6500k bulb and most are in 6-12 in range of the 32 watt cfl. The temperature is roughly 80-85 at the high end. There are two fans, one pointing toward the plants and another exhausting. The humidity is roughly 52% margin of error 7%.
The seeds are bag seed from reggie from a single bag of reggie. He didn't want to risk buying online. We live in America and don't have a clue as to which seed banks to buy from without being arrested.

We are just curious. Why are 4 of the plants growing amazing at 5 weeks into flowering while 1 plant just looks like a lanky plant with TONS of nodes?


Ask any more questions you want but I can not take pictures. I don't own a camera and he and I both believe that cell phones can be used against you since the photo has a long of gps cords and height from sea level.
