strain has little to do with how you treat the plant and neither days an autoflower, with minimal nuance related to to its biological trigger for flower. the reason some struggle with variety is that their methods are esoteric. Instead inward reflection or adapting/adjusting they blame the plant for 'being picky' lol, nope, just a bad fertilizing regimen or trying to be unique instead of competent. simply put - if the plant looks like shit in doors, there's only 1 person to blame.
i've never had problems running 6-7 strains from 1 reservoir and never worried about it impacting the grow. it's not a brag. it's a proof of concept that these plants, despite what people say, are not that unique or special, though i'm sure oddballs can occur, rarely.
so look for diaries with healthy plants from start to finish.. minor blemishes are sometimes going to happen, but it should be limited and short-term issue with any competent grower. Look for those using same methods.. don't focus on a soilless grow if you are using soil, for example.
