Irydyum cheers for that. OMRI? Showing my ignorance here but what's that?

With the biobizz do you use the nutes with ever watering? most growing guides tell you not to feed nutes every water, but during my grow i was getting all sorts of greens and yellow leaves, and when i asked questions (on other forums and in grow shops) i was given a range of answers ranging from nute lock out, nute burn, not enough nutes, too hot temperatures etc.

what i'm confused about is the instructions seem to say feed with every watering but the advice i was getting back was feed max once a week from experienced growers. What's your watering/nute regime?
