In looking at your other plants do not expect to tie down as you did the little bitch.
Your secondary shoots on those plants have already formed and extend out beyond the fan leaves. What is it you intend to tie down?
You dont wanna tie down the secondaries that have already grown...they just need more powerful light, not more of what you already have. That time has passed :)
Perhaps you should jsut chop all the others down and give hardonna her room :) :) :)
Turn her into a 3 month veg and then flower...LOL :)
Those pics you linked are nice indeed...but I wouldnt call them preflowers at all and the ones you will see will look nothing like that....those are full blown flowers and balls.
Preflowers are much smaller, much harder to see than those.
Preflowers also dont show like that at the tips of stalks,...mostly anyhow.
Look for them RIGHT ON THE MAIN STEMS....
She;s looking good....and she's all that matters ....hehehhehehehhe :) :) :)
