Should I add liquid nutrients?

oh, ... shit is it high P that can kill off myco? there is some potential contradictions, but if a plant is deficient, you need to add nutes. call the soil whatever you want, the proof is in the pudding. in other words the plant decides that stuff, not us. if it's deficient, it needs more.

you may need to supplement supersoil. you can adjust ingredients next time to avoid it. Over time you'll evenetually have a mixture of right proportions that can possibly feed the plant all he way to harvest. you 'shouldn't' need a lot of fertilizers. that doesn't mean you won't need some. it takes a few cycles to dial that soil mixture in, i bet.
