I do not see a reason to increase nutrients in your system. Dinoflaggelate can show up in any kind of system, whatever the nutrient concentrations are. There are so many reasons for them.
My recommendation is to continue as planned as long as there are no issues giving the system time to build up a strong biology. Your dosing regimen is fine, continue to use it and replace the ZeoVit material every 6 – 8 weeks and the carbon every 4 weeks if passively flown.
You can also check the ZeoVit reactor flow, should be ~ 400 liters per hour. KH is a little bit high it should not increase furthermore. Try to keep the level in the range of 6.5 – 7.5, please also check the K+ level of your system, should be ~ 380 mg.

Tank Progress and Recommendations
1. Gross water volume of your complete system (incl. sump etc.) - US gallons / UK gallons / liter: 112 gal
2. Net water volume (incl. sump etc.) - US gallons / UK gallons / liter: 100 gal ? (425XL)
3. Are you using a CaCO2 reactor or other technique: new tank/few corals.. H2O chg only
4. Are you using a PO4 reactor (how long, how long ago, etc.): No
5. Are you using Ozone: No
6. Are you using UV: No
7. What skimmer are you using (type, rated water volume): Nyos 160
8. What are your actual PO4 and NO3 levels: 0 RSR Pro Nitrate, 0 ULR Phosphorus Hanna
9. What are your actual Ca, Alk and Mg levels: 430, 8.5, 1320
10. What filtration method do you use (refugium, DSB, Miracle Mud, etc.): Filter floss, skimmer, Zeo Rx
11. Type of light (Watt, color temp, how old, etc.): 2x Radion 30, 3x 360 Kessil, 4x T5 (only running Radions currently)
12. What corals do you keep: only SPS. 3 tester frags currently
13. Tissue color (light or dark): Light
14. How long has the tank been running: 2 months
15. Why do you want to use the ZEOvit system: tank interaction and pastel colors
16. Any supplemental dosing (type, amount, why, etc.): None
17. Live rock (how much, how old, etc.): uncured dead rock. KPAquatics LR on way for additional biodiversity
18. Any present problems: 0 NP, fish fallow period
19. Problem description (tissue loss tips, tissue loss base, diatom bloom, algae, etc.): slight diatom or similar in shaded areas of rockwork
20. What test kit do you use (how old, recently switched, etc.): new N03 RSR Pro, Hanna ULR/Alk/Ca
21. Present dosing, amounts and intervals (ZEOvit, ZEObak, ZEOfood, ZEOstart, ZEOspur2, etc.): Zeovit 1L 4wks, Bak/Food7 2x 4 drops wkly, 0.4 Start daily, 4x 2 drops sponge power wkly
22. Other water parameters and water stability (salinity, temp, etc.): 34-35
23. Which salt brand do you use: Currently using up old buckets of IO and RSR Blue, TM Pro ready when others used up.
What is the recommended way to increase my nutrient level to avoid dino risk? I am currently fish fallow for several more weeks. I have cleaner shrimp and 2 emeralds. Is NO3/PO4 dosing, ghost feeding, or zeovit blue bottle recommended for keeping some trace of nutrients recommended? Only 2 small acro frags and a birdsnest currently.
