Hey brothers, got some plants in soil right now about 4 weeks in ocean forest/happy frog mix with some ewc and azomite and myco. my question is what do i do now that the soil will be running out of nutrients. just about to flip to flower and the plants are around 2 feet tall.

What would you guys recommend for nutirents that would be very easy and a good way to finish to flower ammendments/nutrient wise? thanks for your time. and if anyone knows what height to have 315 CMH from canopy for flowering
