Yup, first time growing a plant! I researched for a LOONNG time then I did more, and I'm still doing more Thank you for your kind words and advice friendFirst time grower? Nice even canopy... good job on the scrog.
Buds look like a decent size for 3 weeks.
Looks like you did your homework. Well done.
Stop tucking when your plant says so, which is when the stretch stops.
