When to stop nutrients

I have a 60 day old white widow autoflower. Using dr earth dry amendments. I last top dressed 2 and a half weeks ago. I know they say to top dress at 3 to 4 weeks but at 4 weeks this time it should only have a week or 2 left. Should I top dress anyway even with that short amount of time left? Will it increase bud size?

I give nutes right up until chop day.

But there are differing opinion on the topic.

.

I feed up to chop as well, but only a fraction of what I give the plants in full flower. I've had some leaf burn in late flower and I'm adjusting the feed.

I don't notice bud size increase during the last 2 weeks, but there is a density increase, more weight.
