Live Stoner Chat When should I start to add flowering nutes?

Hello everyone, I'm 39 days into my first autogrow and I'm uncertain as to when I should swap to flowering nutrients, here is a picture to help you help me, would really appreciate the help as I'm worried about adding them too soon or even too late :S Keepin it green

I would normally reccomend waiting until vertical growth stops to switch to flowering nutes, as long as you aren't in any immediate risk of overcrowding your space.


Your girls have pretty long internodal spacing though. Partly sativa genetics, partly stretch attributed to lack of light it seems. What is your setup? Can you get your lights any closer.
My concern with continuing high N veg nutes is the continued stretching which I'm not confident your plant would support its own weight once the buds come in, if it gets TOO much lankier. You would also have alot of insufficient popcorn mugs on the lower part of the plant

I have them on a 2x24 t5 fixture (above) and an 80 cfl (side). I know it's not the greatest supply of light but it was all I had at the time, they recently slowed down a lot in their height. I have been told a few times that they might not withstand the weight and lean, would holding them up by bamboo or string help them?
