You might wanna start a thread in the sick plants section along with some pictures of the plant and leaves that you say may be showing issues.
I've never used Miracle Grow Organic but I assume it's still not the best for cannabis even if it's not extended fertilized like the regular MG soil. Not familiar with their plant food either but also safe to assume there's better alternatives.
Understand being broke but I can recommend other cheaper options. Menards sells Pro mix Organic soil for around 4 bucks a bag. Maybe grab a bag of perlite and that'll already put you ahead of where you're at. The Pro Mix Organic has organics nutes but you can supplement with Osmocote Tomato feed, plants actually love that stuff as Tomato has similar needs to pot. Also sold at menards/Home Depot.
3 gal is a good size pot for growing a big plant so you're good there.
First couple grows will be rough, you'll get better.
Good luck, let me know if you need anything else.
