I'd advise vaping tbh Yeats, and all I've ever used is organic nutes, previous grows on biobizz and current on biotabs. So yeah there could be ferts there, but surely no less than the buds, specially on a blooming plant, and where it's yellowing leaves due to the girl pulling N, certainly won't have much ferts.
I just let them fully dry out then it goes crumbly/dusty and can be vaped or smoked easily. It's not the smoothest taste, but it's a million miles better than baccy IMO! I know you US dudes don't believe in baccy in joints anyway, but it's v commonplace here in blighty. I've never been into tobacco, hate the taste and the buzz let alone the smell, uurgghh, made me feel sick a few times when i've had the misfortune to inhale.
But if I pass round a pureno bud J folk just go on about it being too strong etc, but just mix in some leaves and brings it down a notch or two so your common or noob smoker does freak out
