My PPM levels are to low. Always around 150 / 200. How do you raise or lower them?

PPM usually a factor of water used (Tap or RO water) plus nutrients. Checking PPM before and after lets you know how much nutrients are left in water. It gets a bit more complicated depending on what you are growing in.  
Soiless like coco or Pro-Mix are treated pretty much the same as  
hydro. Soil is a bit different. Folks will need to know what you are growing in etc. to better help you out.

How old are the plants  
What type of soil you using or medium you in ?  
Have you started to feed them  
Posting a picture in natural light would help us judge your grow also  
@Phoneman49  
Feeding is how you will raise the ppm or using with amended / hot soil once they are are old enough
