He is saying you have to go back to 18/6, reveg, then 12/12, reflower. I have no idea personally... Does sound lengthy... I guess since you cut off all the bud sites, it would have to veg more sites for the new buds to grow...

I see some people cut the larger buds off the top, then trim back the plant and let the smaller buds keep growing, always under 12/12...

It is my understanding that the plants dont really give a care about the light in the first couple weeks or so, as long as they get it... So, I personally change my light to be on in the day and off at night after I move my stuff into my cab. Before then, I run them 24/7 for my seedlings under flouros... After that, I try not to change it again until flower...

Be gentle with babies... Veg for 1 month, then switch to flower is my opinion... Hell, they continue to grow throughout... Plus, I believe, that you will get more females with a shorter light cycle. I am actually vegging under 400MH for 16/8 myself...

Hope another opinion helped...
