See Alot of nutrients are used by some, looking for insight on TPS-ONE

It looks to me like the nutrients you used worked really well for you... and that's the biggest thing, imho. I don't know what you mean by "could have gone harder" - the plant will tell you if it needs more, if it can stand more, if you can push more.. as long as you can read your plant and understand your nutes, you'll be able to make those decisions. In general, if you don't already, you're going to want to really understand EC and it's relationship with pH and that relationship will really tell you what your plant can withstand and what it can't... Case in point is my Devil Cream grow... just screwed her up to a faretheewell by trying to "push" her much too hard - she looked HORRIBLE and the EC in combination with the pH told me what was wrong.... thankfully, I'm growing in DWC so the correction was pretty easy and pretty quick (although she's still LOOKING a little bit funky).. and having an understanding of what my nutes are, what they're comprised of, and how to balance them to suit my lady is what is saving her.... Knowing what to give when and what to cut back on when - all these things that will come in time ... you're going to learn something new with every single grow... you'll have your successes and your failures (and it's from the failures that you will learn the most)... For now, stick with your nutes, learn more about what extra nutes might make a better harvest - like extra P and K in flower (VERY hard to overdose on those) will bring bigger and denser buds... You've made a marvelous start.... now just keep it going! Good luck!
