@growsince79 When you say fourth node. Do you count from the first set of leaves or from the cotyleden and upwards. I usually count from the first set of true leaves though some might consider that the third node. Curiosity.
I don't top usually. Instead, I'm a big fan of LST. I use pipe cleaners to tie the main stem over at roughly 90 degrees. This allows the side branches to catch up which gives you multiple "tops" type buds. The benefits are you aren't removing vegetation so you don't need to lengthen veg time to regrow the lost vegetation. This allows me to flip to 12/12 4-6 weeks into the grow or when the plants are roughly 18"-20" tall.

The pads are 0, the single blade leaf is 1. When I top it's usually about day 14, after the 4th. That leaves me with 8 branches. I cut the bottom 4 off after 2 days, leaving 4 branches. Sometimes I'll top the top 2 branches again around day 20 and flip to flower a week-10 days later. If everything goes well, they make 3-4oz each in 90-100 days from sprout.
