@ BeautifulCraftRreddit; Yeah, the Blueberry was more prone to conditional problems, sensitive to nutrient burn, etc. And it was also the first to hit flower-fade at the end of its time. It helped convince me that it wasn't the best to run 3 different strains at the same time. At the same point, if I'm running 4 of the same thing, it's easier to tailor the feed to that one strain, and dial that in, I think.
On the other hand, I have 8 NL seeds (I originally bought 10 NL, and 5's of the others). And those plants just GREW the best. Once I got used to them, they did well and even with all my abuse they were very forgiving. The Tangerine Dream is the one strain that's heavier on the Sativa...but the one I grew was really dense and tight and was a mutant that only ever developed 3-lobe leaves that always pointed downwards. So this round I ended with a bunch of reasonable indica heavy stuff and less sativa, so there's some draw to balancing it out. I'm going to move to Pro-Mix and stay with all my other common elements but get some good myco for next run. I'm also going to start out in .75g pots instead of cups.
