Ah dude please don't get me wrong, they look great, you are to be seriously congratulated for growing full stop let alone plants as healthy as that.
I do believe, as it's your first grow, (no idea how many I've done, lol) a wee bit of advice is required so you can get more out of your plant;
Can you see the difference in the leaf color in picture 2, the younger leaves are bright green and the older ones are blue / purple ish sort of hue, and purple/red leaf stems . . . . .
Your plant would really love you if you upped the amount of Phosphorous you were giving her
, if you've got P in it's lone form, just water through about 0.4 to 0.5ec with your next watering or add that sort of e.c. to your feed if that's next.
You're doing bloody great, far better than my first grow, back when . . . . . errr dunno, cant remember . . . lol
