all of the ec meters i’ve seen are quite expensive. are these a necessity for my autos to flourish? would a good fluke multi meter work for this? if so how would i go about testing? i am new to the indoor grow,and would like to give my babies the best possible care for a successful first time experience.
You’ll need a Tds or ppm meter and a ph meter both you can pick up on amazon for around 20$ ea
And you should pick up something to read temp/humidity also available on amazon for about the same or less .
Hope this helps 
Happy holidays

I personally would say no especially with your basic soil grow, but they do come in handy. If you follow the instructions on your nutrients, with a basic understanding of how plants use their nutrients, along with reading how the plants & leaves respond, you can get away with not using any kind of TDS/EC meter.
