I honestly don't have any cents when it comes to autos, she's taken my auto virginity lol. I don't plan on giving her any nutes until she's in full bloom, I've heard a lot of the die hard auto growers say to keep giving veg nutes for the first week or 2 of pistil's.
Seems like not a bad strategy for any strain, at least to an extent whilst slowly ramping up the bloom component, at least if/when a plant isn't already overloaded with nitrogen. The stretch phase generally occupies the first 40% of the flowering cycle, and must require nitrogen.
That's a general statement. I'd be afraid to talk nutrients about Dark Devil Auto, specifically. I
think I read a comment by Rifleman in his journal thread (or in this one?
) about how, in a DWC grow, he kept lowering the nutrient amounts on them and was still seeing minor burn. But I might be confusing him with another gardener, DDA with another strain, or this loaf of bread for a keyboard (asdfjkl; - nope, it's actually a keyboard, lol). It has been one of those days.
Plus, I have read that one's nutrient formulation can affect the time it takes an auto-flowering strain to actually enter the flowering cycle; way too much nitrogen causing an extended vegetative-growth phase and immediately switching to a hardcore flowering nutrient schedule (in other words, no transition/blending) causing the gardener to end up with generally smaller plants and less yield than he/she should have at harvest time, that kind of thing. IDK, I've only grow a few, the first ones were afterthoughts that I had no love for - and expressed that in my care for them - and the latter ones were treated with a combination of laziness, clumsiness, and...
gentleness(?), meaning they didn't get fed much at all. I was just looking to see if they'd make it to harvest in Mountain Dew bottles (yes, of course) more than anything else.
