How and when with Autoflower

I'd chop it at the second node (aka top it). Then tie them down, It'll be a lot easier to handle (the height) later on. Add a Scrog net if you wish, I usually do it. AND PLEASE DON'T BE AFRAID OF HST AND LST THE PLANT. IT'LL RECOVER!! AUTOS CAN BE TRAINED! XOXO Cremo

I start training as soon as the second node starts showing. I like to keep it low and tight to the ground. I continue to train until preflower.

Do not top, your plant will not have time to recover as you are already about half way through the veg phase. Instead do low stress training (LST) to create more bud sites by spreading the plant out horizontally. I would start low stress training now. It can continue all the way to harvest if needed. A fabric (not metal) screen is better than a metal screen. Metal is unforgiving and can damage the plant. There are many, inexpensive stretchy nets made just for this purpose. I do not use a net though as it prevents you from moving the plant and makes access difficult. Instead I use a soldering iron or I heat a nail and melt a series of holes around the top of my fabric pots. Then tie your plant to these holes. That way you can do LST and still have the ability to remove a plant from the tent or to rotate it for better access to the other side.

Awesome thanks guys will start lst now do you suggest topping an auto for more top colas bare in mind these girls are autos... I have a metal screen for scrog use a bit later in veg early flower. Have min height so trying to maximize lower branches aswell as cola sites at top.

I would start now, I also keep up with lst thru out flower, ive find it to help with more surface area of light to hit

Start any time, but go slow on the bends to not stress her too much., and when you get her to the shape you like then let her go. Usually start to flower in 4 to 5 weeks with very little stress so I would stop a when you see some signs that flowering is about to begin.
