I started my frist grow with 2 plants. Ive been using the same soil, fert, and same place for both. However one plant is really gettin bushy and not as tall as other but looks really healthy. The other is growing tall and not bushing out.. however it leaves get yellow spots on the new ones. The new leaves look fine for the first few days of growth and then when they are like 2-3" yellow spots start to appear. Then as they mature they begin to turn brown and the tips curl down. Im using the same everything so how can one plant be so healthy and the other not. Can anyone tell me what wrong..ive added a pic.. please help

Whats up Wilson. You need to find out the PH of your soil and the temps of your grow room. These can be major factors in your plants problems.
