I thought when you added nute's to water that was supposed to raise your ppm I have a meter checked water other day it was at 450 I added some nutrients since I read that ppm should be around 600 to 700 during veg my ppm went down to 120 ish after adding nutes. do I have to wait awhile before checking water or something?

Also if your base water reading is 450 you need to buy water or an RO system.

My PPM meter has a 10x function, whenever the PPM goes over 1000 the meter drops a digit and flashes a small 10x in the corner.
you might want to check that.
