You don;t need CO2 for EI... you can try the EI "light" version...
Or a modified EI targeting 10ppm of NO3 and 10ppm of K weekly, 3 - 5 ppm PO4 weekly and then two or three doses of CSM+B or another micro fertilizer targeting 0.15ppm Fe. Large 50%+ water changes weekly...
Or go with the PPS-pro method..
