Failed Fimming-What to do now?

If the lower node doesn't also come with a weak pull of resources (weak apical dominance), avoid that as it'll never catch up without excessive effort from you trying to slow everything else down. IF it's close enough to the top to demand resources or easy enough to temporarily bend other stuff to shift resources, sure. FIM is inconsistent. MAybe, you can get 'good' at it, but it will never be 100% predictable. I'd be skeptical of anyone who says they can do it in a consistent way. It's like listneing to people's gambling stories... you only hear about the successes. Asymmetrical growth may reduce potential? damaging 2 axillar buds instead of 1 has potential cuase for difference. Would just be a good hypothesis to test and not certain. I think the multiple axilla come from a 'fraying' of plant material... 'enough' on each to promote new growth and heal around each, which may not matter as far as symmetrical vs asymetrical growth (1 vs 2 branches per node). Do it enough times and i you might get a glimmer of the answer, but still a lot of other things at play that create a fog of war. if having fun, knock it out, but imo better to have a plan for the endgoal canopy and reach it in a systematic way - reduces your time, effort and resources invested. FIM can't be trusted or counted on. Even when it does work you get a variable number of branches. Therefore it's just a gimmick to play around with but not a viable standard procedure, if you want more consistent results.
