Soil Mix/Nutes

I'm on my first small indoor grow from mexican bag seed. I have a good soil mix (Premium Top Soil, Perlite, Lime, Bone and Blood Meal, and worm castings. Plants are doing well (healthy) and are 4 weeks old. My question is do I need to add nutes to the plants in this soil mix? I read that this soil mix is all the plant will ever need. I don't have time for a second grow and I'm trying really hard not to screw this up. Thanks in advance.

Your plants will almost certainly need more nutrients. I've never bought a premix that could feed for an entire grow. I would highly recommend looking into some kind of fertilizer. If you decide to go for dry fertilizers over a liquid, you'll have to add it early to get the full effect. Never used them bottled nutes personally so I couldn't make any recommendations but Down to Earth has great dry fertilizers if you can get em' in your area.
