That's top soil. No sense in telling you to add compost, etc., since you are using chem nutes. But the nutes will work, I would wait 3-4 weeks before adding 1/4 strength. I would add some perlite and maybe a little sand to that top soil. Actually i would just go to wallyworld and get a $4 bag of potting soil. I hope you have a smoke detector, that looks a bit dangerous.
