it's a measuremented of dissolved solids in a liquid. It measures the electrical conductivity of the liquid. The more dissolved solids "ions" the greater the conductivity. Most ppm is based off of this measure. There are different conversion factors 500/700. ex. (.1 ec = 50 ppm)/(.1 ec = 70 ppm)

To answer Yes

are you checking your ph regularly? The leaves that are damaged will not always repair themselves. You should be looking at the new growth for changes. Plant looks ok, I think it will recover

not really aggressive, but yes I think it's a huge part of your problem. Sorry just input. Didn't mean anything by it

I would have to say your issue is either water (chlorine can do weird things), or soil. How do you check your ph and what kind of water are you using? Maybe try adding some lime and a bit of perlite to the soil. I find soil from outside when put in pots tends to settle and be not so airy. Just...
