For what it's worth, Miracle Grow Organic Choice has low nutrient level (0.10-0.05-0.05). I've seen people on forums say they use it all the time. It's just the other varieties of MG potting mixes which can be hot, with slow-release fertilizer (every time you water, it gets worse).

Another popular over-the-counter (retail store) potting mix is Black Gold Natural & Organic (0.05-0.0-0.0).

I haven't used either, but I'm thinking of trying the Black Gold soon. I would add perlite. Probably a lot (50%). I think cannabis likes to go from wet to dry pretty quickly. All the potting soils seem too dense/heavy (IMO). But, I grow in amended, organic-fortified soil. I feed each watering, and don't expect the soil to have a lot of stuff in it. Maybe it would be different with a rich soil.

Why would you add perlite to an already horrible soil mix like Miracle Grow or Black Gold? In fact, why would you add any aeration amendment at all? If anything, a good compost needs to be added at about fifty percent of the mix. And if you for some reason needed to add aeration (although I have no idea why you would), add pumice. Or maybe lava rock. Perlite is garbage. If this is what you’re doing, it makes sense that you have to “feed” your plants every day, just because it sounds like your mix is pretty much perlite and nothing else. You might as well be growing hydroponic with a perlite-heavy mix, which you basically are. And BTW, cannabis absolutely does NOT like to go “wet to dry.” At all. Cannabis and the soil it’s grown in likes a consistent medium that’s neither too wet nor too dry. Let it go dry and the soil (and therefore the plant) is not happy at all.

I've seen people grow in them. I don't think they're horrible. I find that cannabis prefers light, airy soil (fast wet/dry cycles). I like to feed the nutrients instead of having the nutrients in the soil (more direct feedback to what I'm feeding).

I recognize there are other styles of growing. Good luck.

@az2000 and @GarciaGrows Feel free to google Miracle Grow organic choice (?!?) and read some of the reviews. You might wanna take a look at that before you go suggesting that garbage to people.

Yeah, I don’t worry about “feeding nutrients” to my plants at all. The soil does all the work. Gotta love growing organic!

Was the temperature significantly lower during the 48 hour of darkness?
