I always use Miracle Grow on my vegetables. The bag says to do half MG and half soil but I use a quarter MG, quarter Perlite and half soil. I never had a problem with tomatoes, peppers and squash.

Just remember you do not have to fert for at least a month and never start a seedling in MG, wait 2 weeks and transplant into the above mix. The only problem I can see with MG is that it feeds for 3 months and that would in most case run into flowering stage. So when you use a BLOOM fert you might want to use it sparingly at first or really flush your plant going into flowering. Trace elements have been a concern with MG from some articles I have read but with my Veg. Garden I have never had an issue but I do add Epson salt from time to time.

Basically you have no control over the ferts in MG and if you do not have a problem with that it should be fine. If you like to control every step of your plants life, use a fert made for Marijuana plants and by some good soil that has no ferts in it.


I hope this helps
