It’s quite possible to PLEX 2 accounts with semi-passive income from Planetary Production; however you’d need more than the four (4) alts you currently have, my guess would be that you’d need to utilize all of you available slots/characters (I assume you have 2 main + 4 alts?). With 6 characters you’d have upto 36 planetary setups at your disposal. Have extraction planets (Raw --> P1) and a couple of factory planets (P1 --> P2-4), there are no right or wrong way to do PI but you can optimize it a fair bit to maximize your production and thereby also your profit.
