Run off PPM 2300 in veg?

FFOF soil
7 gallon pots
2ml FF grow big nutes per gallon with 2.5ml cal mag at the same time for a total of 150ppm watering
Plants are roughly a month old and are doing good. I just got into PPM.
I know that ffof runs hot so I didn’t bother to feed heavy at all but I’m only putting 150ppm in once a week (plants get watered about twice a week, and this will have been my fourth watering). So twice they have been fed, the other two times plain R/O water.
Anyways, PPM is 2300 on run off. Everything I read says that’s too high for veg but the plants are doing great. My larger of the two has a slight rusty spot on a couple of the bottom fan leaves but other than that they are great.
Would you say just leave nutes out of the equation until PPM runoff is low?

thanks.

Why are you testing runoff in a soil like FFOF? Worry about what goes in. Are your plants healthy? If so then leave them alone. Don't go flushing a bunch of water through your soil trying to get the runoff PPM to match some magical number you read about.

I’m reading runoff because there is a ton of information out there about every aspect of growing including testing run off. I’m not worried about it, I’m just asking a question. I also have not flushed my soil, that would be kind of silly now that I just said I fed them.

My understanding is that testing runoff is for coco, not soil. I grow in coco and really don't bother testing the runoff anymore, just learned how to feed them properly. You would be better off learning to read the plants and their signs than you will reading a meter result for what came out of the soil.
