Self mixed organic soil with lots of ingredients ^^
It had compost, vermiculite, perlite, mulch, azomite, rock meal, fish meal, sea weed, leonardite, a little bat guano, some sulfur for long term pH regulation, some of the last plants as green manure, epsom salts... but not much of anything. And none of the plants showed those nitrogen claws, only the "Purplematic"s...
I added nutrients to the water first time two days ago... I used Canna Mono stuff, mixed it 1.5:2:3 and EC 1.5...
