My boys LST thier plants after the 12/12 but not too much of a hook in it.

Too much LST will stress them to the point where it will produce seeds.
Of course, so will burning them with your 400W HPS!

Growing too tall is a real problem and should be managed while in the vegging stages if possible.
FLORIDA MON Reviewed by FLORIDA MON on . LST after flower? Can you still LST your plant if you have already started the 12/12 cycle? For example if your plant is growing too tall and is in danger of being burned by your 400W HPS light? If you can LST the main cola, is it going to negatively effect amount of buds?
