What’s the thoughts on topping, this is my first go at a Scrog and I’m unsure when I should top and start LST - my plan is to wait a few more days to strengthen and the top on the 3rd node
If you do fim , it is best to leave the plant at least 10 days before flipping to 12hrs.
This will give each new branch a chance to grow enough away from each other to define themselves .
Nice looking canopy 👍
About the topping the best moment is between the 5th and the 7th node and about the LST the best time to start is when your stems/branches will be long enough to be bent. You plan seems to be good but I would have top a bit after the 3rd node 😊👍
Wait Until Plant Has at Least 3-5 Nodes (FIMing) or 4-6 Nodes (Topping)- Topping or Fimming a Too-Young Seedling Will Dramatically Slow Down Growth. If You Wait Until Plant is Growing New Leaves Every Day, Recovery Will Be Much Faster. Looks like she is almost there though.
