I dont really get ppm please help

[lungbutter24]

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?

Something is mos def wrong. What brand and model meter is this?

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

Yes PPM or EC should rise with any additives. If your base is 450 (Heaven forbid) it should be well over 600 with even a half strength feeding.

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.

Easiest way to ppm - measure out one mil of ferts and add to one litre of water and take ppm reading.

Now you dont need a meter as you can just work of ml/l and by virtue of simple maths always know you ppm.
