i have some chemical, and some organic, as im in the mode of swtiching to all foxfarm products, but the organics i would feed at full strength of recommended dose... as for the chemical nute, i feed at 1/4-1/2strength as recommended... every 1-3 feeding i water with plain r/o water w/ 1 tsp of cal mag.
