1) Welcome. Cool people here. You'll like it.
2) Carl Jung had a lot to say about modern's man's fascination with team sports. Geeks one, jocks zero.
3) Your fertilizer question: the answer isn't so simple. Plants need different amounts of different nutrients at different stages in their life cycle, and that's before you consider other environmental factors (how much water are they getting, and how consistent is it? What are the temperatures? etc) And if your plants AREN'T nutrient deficient, overdoing it on the fertilizers can cause more harm than good. Upshot: if it ain't broke, don't fix it, but judicious use of a blooming fert while your plants are setting isn't a terrible idea. Just be aware that the fertilizer your friend suggested is a "complete" fertilizer, not a bloomer.
Oh, and those aren't Reapers. Sorry to be the bearer of bad news. When it comes to sourcing seeds, check out the vendor vaults on here or ask around. There are more than a few vendors with a reputation to lose, and those are the people you want to buy from.
