How many sets

i was just wondering how many sets of leaves a plant should have at about 5 weeks from seed

Answer...as many as a healthy plant has. There is no way to answer this, every plant is different. I have a feeling you are concerned about something you perceive is wrong with your 1st grow. Please check the link on my signature. A ton of great info on video for first time growers, from grow masters. Best of luck.

yep every plant is different and different lighting can tighten the distance between nodes
