Thanks man.. We'll see how these works then.. If i notice any change then i will put those back in... Should i start to flower that guy yet? i have 3 plants in that room now and its gonna get crowded! id rather find out if its a female and then focus on her ! ! is she big enough where i can do that?
Are your seeds feminized? Did they endure any crazy light/nute/water problems/stresses? These both affect sex of your plant. I can't tell from the pic if it's showing sex yet.
For whether or not to flower yet depends on a few things:
1. When do you want them to finish? Take your ideal date and subtract the seed bank's estimated flowering period from your final date and you have your "begin flowering date".
2. How much room do you have? Indicas tend to double in size during flowering and Sativas can increase three-fold or more during flowering. Take these rough guidelines into account.
3. Are you going to LST/SCROG them? Great not only for yield but height control. You can manage otherwise huge plants with these techniques.
4. Is it an autoflowering strain? If so, it'll flower whenever the hell it wants to. It doesn't give a fuck when you think she should hit puberty haha.
5. What does the seed bank say about height? Seedbanks give estimates on indoor and outdoor heights although the outdoor is really more relevant because you have control over the light cycle/flowering period indoors--which directly influences final height.
But to answer your question in a word: she is plenty, plenty big enough to begin flowering. Some people even skip the vegetative phase completely and begin flowering from seed on a 12/12 cycle. I wouldn't go to this extreme as most sources sight a recommended minimum of 1-2 weeks of vegging as this period is crucial to the hardiness of the plant. The buds are no good if your precious plant topples over. You've been vegging for some 3-4 weeks now? You will have no problems switching your light cycle now.
Note: Consider your plants as a whole group and think about when to switch the light cycle so as to maximize the yield from all your strains en masse. I am currently in this predicament since I have an autoflowering White Dwarf who is about a week into flowering and an Amnesia Lemon (light cycle) who is about 3 weeks into veg. I want to start flowering my Amnesia Lemon but by doing so I will have my White Dwarf flowering on 12/12 *tisk tisk. So, I am going to let the White Dwarf finish on the 18/6 cycle and veg the Amnesia Lemon the entire time. Right when the White Dwarf finishes, I'll take a clone from the Amnesia Lemon and Start Immediately flowering both of them. They'll get unwieldy but I'm gonna LST them to no end. As you can see, light cycles can sometimes be a puzzle when you're dealing with different strains/subspecies, especially when they're all in different stages of their lives and you only have one grow box/room.
I know this is a lot of information but I hope it helps you decide when to flower. Short answers aren't often complete answers when it comes to tricky questions like this one.
best,
