two days later they're really starting to take off...organic super soil is hard, very difficult to get it right for indoor cannabis IMO. These seedlings were almost dead when I transplanted them 8 days ago.
I've been experimenting for 2 years trying to get it perfect, I actually paid for an hour-long consulting session with a professional agronomist at one point. He had a different take from most of the chatter on the cannabis internet - he doesn't like compost in containers. He said keep it to 5% or less, and that's where I've ended up.
Compost is heavy and holds moisture on the roots which cannabis doesn't like. The release of nutes from compost is unstable and unpredictable. I've been adding 3% worm casting thinking it was safe, it took a bunch of growing cycles to figure out that it was nuking my plants. 3 weeks after planting it would release a ton of nutes and suddenly the plants would burn up. Couldn't figure it out until I eliminated everything else from the mix. Last month I lost my flowering crop of C99XCannatonic this way, I started another batch of these seeds, can't wait to use the good mix on them.
