Out of the tap, my water is ~100 PPM. I'm feeding 1/4 of recommended FF trio + Beastie Bloomz and the PPM is ~300 going in and ~600 coming out. I'm assuming the difference is from what's in the ocean forest soil. Am I feeding enough? Should I add Cal-Mag?

you should definitely add cal mag, especially for the magnesium part of the equation. I notice some leaf cupping, doesn t look like much right now but that's bad news, you want to add something like enzymes to your mix and chelation agents like humic and fluvic acid to try to beat what I suspect is a root problem. Hope this helps ! :rocket:

Your base water should be around 200 to 250 PPM: if your tap water is below that (like yours) you should add cal mag to compensate. It's hard to say if your feeding is enough or not, since it depends on many factores like: soil amount, light, etc. If you are seeing deficiencies, then it's clear you need to up the feeding. What I can see are calcium deficiency (rust / copper spots on upper leaves) and potassium deficiency (uneven yellowing with some rust spots on lower leaves). Also your leaves are dark green, which means nitrogen toxicity (where you feeding grow nutes recently?) That could also explain the edges of the leaves cupping. The cupping usually happens due heat stress when the lights are too close.
