I start with RO water at 0ppm and after I mix nutes I test ppm again and it's always around 500ppm. Is this enough or should I be adding more nutes, I've seen some say theirs are around 1200ppm. I'm growing in soil happy frog/ocean forest/perlite mix. I'll add a pic of nutes I'm using.
Ppm after nutes?

Feed according to what the nute manufacturer says for a soil grow at the applicable stage of growth the plants are in. Measuring PPM is more for coco/hydro than soil.
I would definitely keep checking ppms even with foxfarm soil.
Always add cal/mag first. Stir and wait 5 mins until adding other nutrients. With Ro water, calmajic recommends 5mls per gallon. But I would start off 3mls when they're younger.
Definitely keep your PH inline too. You should be fine with 6-6.5ph
1200ppms are for really big plants that are typically in flower by that time.
Rough estimate PPMs on maturity:
Seedlings 100-200ppm
Veg 200-800ppm
Flower 800-1000ppm
Water/feed until runoff everytime
A lot of folks run Ocean Forest with Salt base nutrients.

Do you recommend flushing with plain ph'd water after every 3 or 4 feedings?
With coco or hydro yes, in soil, no unless you give them too much fertilizer. pot dislikes soggy soil. bad ju ju.

In soil it is common to use a feed/water/feed/water schedule, giving pH adjusted water every other time inbetween the nutes. The reason for this is that the soil will capture roughly half of what you are feeding them, for the water only pass. This schedule also helps the soil stay clean and avoid lockouts from excess nutes. If you don't alternate water and feed, you will be wasting a lot of feed and clogging up your soil.
The water only pass is not called a flush by those in the know... a flush is something else, it is how you clean soil that has been getting nutes for a while and that is starting to experience a salt lockout, because the by product of your nutes becoming available to the plant, is salt. This salt will continue to build up, and eventually it needs to be removed. We call this flushing. It takes 3x the size of your container in fresh water to properly flush your soil. Most chelated nutrients will benefit from a flush 2 or 3 times during the grow, typically when going from VEG to BLOOM, and then 5 or 6 weeks into bloom as you are nearing the end.
No flushing, just water until runoff.
Plain ph water every 3rd, so feed,feed, water
Especially, using GH
I used to leach my soil (think flush on steroids) between grows and re-amend it, but drought has made that undesirable so I use it for 2 grows, throw it out and start with fresh soil. Next cycle I'm going to give Roots Organics Original a try as I've heard good things about it.

That's the combo I use religiously up until flower. But I grow in coco now is why I use cal/mag. I did use that soil and I would go easy on the nutrients. Your soil should have enough for the plants for at least three weeks. I always follow the GH feed chart and start at 50% strength and move up from there. I raise my ppm's the minute they show signs of hunger. I have learned I do just as good or even better going easy on the feedings (and the bottles with skulls and shit on them). I am able to keep my ppm's down to around 800 at the most during flower and 600 average through most of veg.
