I recently topped two of my plants. They both had reached the fifth set of leaves. On one plant it worked perfectly and on the other - well it worked but it did not grow as expected!
When I topped the plant (with funky growth) it sprouted on the two sides like it was supposed to. But it continued to sprout through the main stem as well. Now I have a cluster of leaves where it was topped. Everything seems pretty healthy otherwise - I got tons of growth at the stalks underneath as well.
I legit didn’t know that lol. I’m actually starting my attempt at a Scrog in a few weeks when my others finish so I’ll be all over these boards making sure I trim her properly to maximise the 2x4 space
