Currently finishing up week 4 of veg on these white widow ladies. Topped both last week. I'm trying to go for a big yield. My first grow only came out to an ounce and a half. This is my second grow and now that iv worked out my issues from the first time around, I'm looking for the best advice to possibly pull a lb off of a plant. Thanks in advanced to everyone in this group as well as Chris himself. When should I top again?

LST to widen the plant as much as possible and then you can top those branches again. I like to do my 2nd top at the branches 2nd node as long as I see growth at that node.
I’d top at the 3rd node of where I topped top the first time and if you looking for bigger yield I’d do LST
This plant has never been topped
