Lol. Beautiful tits, huh? I can see your point, but for me, I'm just slightly more of caboose man myself.
To question one: I have the GH feeding chart (they give it to you free at the hydro shop). I used to follow the chart almost to the letter (except PPM because the aero element of my system made them need less than what the chart said) and that worked pretty great. But as I grew more and gained more experience, I realized I could play around with the suggested proportions of base and additive to sort of customize the mixture to a given strain. These here girls are super hungry and super powerful, so I'm exaggerating the mixture proportions beyond what the chart says. The chart will suggest a solid base proportion of mix appropriate to the point of the plant's life cycle... but it's really fun when you start tweaking the mixture to suit your current grow.
To your second question, Yes, I would say I'm pretty close to harvest, but I can also say you'll probably be looking at my journal for another four weeks or so. After four more weeks, the plants you see now will be a distant memory and they will have transformed into something pretty different looking. At this point, I can only guess how they're gonna look when they're done, but what they've shown so far is very promising.
Plant gazing (especially if you're high off your ass on OG all the time like me) can get quite addictive. But after you complete a few grows, you do worry less AND stare less. But I still stare, don't get me wrong, just not nearly as much as my first few grows.
