Definitely not for seedlings, and not the greatest for any life stage. Pick a soil that is labelled for seedlings for your um seedlings lol (how many times can I type seedlings in one post? SEEDLINGS!!!! mwahahaha)
THen look for a pretty plain potting soil without added fertilizer, that is nice and light, with plenty of perlite in it. If you can't find that, no sweat, perlite is sold all over the plae and you can add your own. Even the Miracle Grow Organic works okay if you add extra perlite! Just be careful, added ferts in the soil tend to interfere with your normal fert schedule, and they aren't designed for cannabis (MiracleDro anyone? lol)
Read the link in my siggy... lots of info...
