don't know much about outdoor grows but your plant looks great, don't worry about it's size, some will be short, some will be tall. Yours looks healthy that's all that matters. It doesn't look like it's lacking nutes but can't see a week dose doing it any harm just use some proper stuff that guys here recommend.

Good luck!
hudson88 Reviewed by hudson88 on . Need some opinions on my first plant It's 2 months old, 45 in. Height, and growing outdoors. How tall are plants usually at this age and does my plant look heathy ( I think I need to add nutes).292390 Rating: 5
