Hello Puppylove, like our fellow growers said already you can bend them down. But be CAREFULL!!! after the preflowering streching period the branches become hard and woodlike. That means that they bend less easy and break a lot faster!
Am growing blue kush my golly they just don't stop stretching am using lst as in near middle of 3 wk of bloom an do not want to disturb to much how much longer will they grow they are averaging 3 to 5 inches per day using vitalink nutes
Hello Puppylove, the rapid growth stops around 3 weeks after you notice the first signs from flowering. This stage called pre flowering stage and it is easy to know for a next time that Indica plants double their size and Sativa plants triples their size during this stage. Enjoy your grow!
