Your friend is not credible. I mean he/she doesn't know anything about growing by stating something that dumb. Don't listen to idiots just learn by reading grow logs on here where your able to read a log and go back and review where they think they went wrong and how they fixed different things. You will absorb actual knowledge from people who don't talk but do. And soon enough you will know what works for you based on your own experience.

I don't like Miracle grow soil but it will work just fine. I like to feed my plants nutes based on when they tell me they need something. MG with nutes is something I would only ever mix into a few mediums together to get what I want. The organic stuff is good for someone who is beginning to grow if your without access to other options IMO. Some people try to feed plants way to early and because Miracle Grow that feeds for 3 or 9 months is what some people use they can over feed and kill their plants. If you use common sense and back off the nutes until farther into the grow it works just fine IMO. I like promix and foxfarm and happy frog soil, but you can use damn near anything as long as you have an extra helping of common sense.

Oh and when your 3-4wks in, your plants will then be mature enough to show sex. Some faster or slower then other strains. There are some closeups of Preflowers in my logs as well as tons of others on here take a peek. Your pics show nothing regarding sex or even type of MJ you have. You need to either hop into a time machine going forward three or four weeks or just sit down and smoke one and chill out. Your pics show usual vegetation. do you think MJ is a plant that is a main stick with just leaves? Branches my friend there the beginning of a plant that is going from seedling to a plant nothing more. I would like you to read thru the faq and growing basic stickies on this site....if you do I doubt you will have many questions until your plants stink like a raccoon humped a bag of fruit! Good luck
