And the Crystal Meth I screwed up badly as you can see from the nutrient lockout which stunned its growth and developed airy buds, low yield and the buds don't have homogeneous effects and most feel weak.
However, once in a while a CM bud turns out good and I mean really good, like one of the most inspiring smokes and a total sensation of happiness and it also lasts a long time, so I can totally recommend it and just don't abuse nutrients, in fact, don't listen to fast buds recommendations on it being a "nutrient-hungry" plant.
Now with my second growth I'm having excellent results on other autos and using very little nutrients combined with just tap water with no nutes.
