They look great. Your buds will add a little more than 1/3 of their weight in the last 2-3 weeks. On an indica heavy strain, this should begin sometime around day 40 of flower. On sativa, you could be looking at day 65. And of course, everywhere in between for hybrids.
As far as the net goes I'm pretty sure people keep them on til there bear fi ished? I've never scrooge though so I can't guarantee that is the right answer
looking really good man Real nice buds. Doing great. Not sure if this is what you meant but hopefully it answers your question. Also by the way if you haven't already getting rid of those tiny popcorn buds on the lower branches can be taken off to maximize your tops more.
Keep the scrog net, it will provide support as your buds swell up. If they get too tall, you can add a second net for more support. This is a pretty common practice, your buds won't get tangled. Cheers!
