Soil and nutrients

Since you’re growing auto flowers you really don’t need a seed and a final soil mixture. If you balance the soil and plant in the final pot you’ll be good to go throughout the entire grow. Autos don’t need nearly as much nutrients as photoperiod plants do so this is why a light mixture is key! I’ll just give you a simple recipe without peat moss because it can be hard to find. Ratio 1:1:1 (1 part medium, 1 Part compost, 1 Part aeration) 1st Part: Coco Coir (I prefer canna coco) 2nd Part: Compost (50% Worm Castings, 50% General Organic Ancient Forest Humus) You can use other composts but make sure you cut it with 50% worm castings or vermicompost. Worm castings are very gentle form of nutrients for a plant whereas some compost usually manure based can be pretty “hot” and high in nitrogen which can burn seedlings and autoflowers. I recommend ancient forest humus because humus is technically old compost which doesn’t really have nutrients but more so has tons of fungi, beneficial microbes and bacteria and also helps aid in aeration and water retention. 3: Aeration (95% Perlite, 5% Bio Char) If possible add about 1 Tbsp of mycorrhiza per 1 cubic foot of this medium. I also to prefer to add about 2 Tbsp of granite powder and 3 Tbsp of basalt per cubic foot of soil. Now keep in mind this will not be a water only soil and you will have to feed occasionally with liquid nutrients, dry amendments or actively aerated compost teas (which can be made with the ancient forest humus and earth worm castings) I hope this is helpful to you!
