Hey Nathan, no need to fret on the nutes here are some suggestions if international brands are unattainable such as advanced nutrients or Bcuzz. If you do have access to general hydroponics, there basic 3 part (bloom micro and grow) have very time tested results

All three are added together in the bubbling resoivoir, following the feeding schedule on the back of the bottle. In addition, you will need to get some kind of enzyme agent to keep your system clean and ensure proper nutrient breakdown, in addition to removing old proteins. I personally recommend sensizyme from advanced nutrients (which you can order online) but hygrozyme works well too.

Now, as a final step, this should cover your veg stage, but when you switch to flowering, there are trace elements that your flower needs, and in order to prevent deficiencies, you will want to have a bloom enhancer. Again, advanced nutrients in my experience has had the best results, Bud Candy specifically, but another good one is General Organics - Bio Bud.

Hope this helps!
ps, most systems that you buy from stores come with very limited airflow (most pumps and stones are made for aquariums, not hydroponics...

), and you can put as many good nutrients in your system, but unless your roots have optimal exposure to oxygen, will not break down their food and not grow! For this reason, i recommend quality airstones and an airpump that diffuses the air so the roots uptake it faster
