one old timer from Aussie before told me that CPs like cephalotus,helis,nepenthes loves high nitrogen to be feeded into its traps.but it seems that the nitrogen level is low and its specialize for blooming in this fert.
u can try experimenting on small neps or neps that u will like to risk and see if theres any more growth,or bigger pitchers etc etc..
and tell us the update!
Thanks
