@aliamyz: here we go again
, try to check out this website, got it by a reference from a forumer at 'carnivorous plant"
http://www.progressivegardens.com/gr.../plantnut.html, got a complete guide over plants requirements for proteins, amino acids, enzymes, vitamins, hormones, chelates and the roots thing explain widely here and foliar feedings as well.
@kentosaurs: fertilizing is good to some extent, do some research, use light dosage at first, usually for neps 1/3 of the recommended dosage for regular plants. Why leafs burned? when do you fertilized? the best time is early morning before the sunlight get too hot. The leftover fertilizer on the leaf will cause the burnt. Also the 'leaf stomata' is opened up in the morning to get nutrition needed for the plant and getting ready to "photosinthesis". Do correct me if I am wrong here.
