Feeding

in my experience a plant does not need a drastically different concoction in bloom... the same upper levels of concentration for K are similar in each stage, for example. I see toxicities at same point, regardless. So, i believe this long-held belief is just another similar to "flushing at end of harvest" myth that some people perpetuated without the equipment and effort to prove their beliefs are actually tied to cause and effect of reality... just "felt it" from experience involving numerous changings variables that would be impossible to resolve with any certainty. so, give enough that you don't see toxicities, as with anything else. if oyu see toxicities, dial back.. plant dictates.. not (sub-)cultural beliefs based on extremely imprecise anecdotes. if the plant has toxic symtpoms, that means it's metabolism is not keeping up with the inputs... plants are not foie gras.
