Thanks for the response man, ummmm...... I switched to 12/12 bout 2 weeks ago and yesterday morning it showed its sex ( female of course ) so they haven't started budding yet I just wondering will they not bud or bud real slow until I give them flowering nutesI don't think a day is going to harm them, but you should get some bloom nutes in there soon. How much nutes are still in them? If lots, then gradually add the bloom nutes. Keep an eye on your ppms and ph for high levels.
i have actually heard that waiting 2 weeks into 12/12 is fine... i fed mine ff grow big until the 12th day of 12/12, when i gave em ff big bloom
