This may or may not help but the one thing I've noticed while reading about autoflowering strains is that they all seem to like light to moderate nutrient levels. Is that the common consensus or am I off-base with that?
Anyway, with that being said if you maximize the nutrient regimen you're used to on autos I'm sure you do just fine!!
lol temunator as we have already told you a few times, start with a half measure and work your way up from there gauging how your plants are handling it
