Is my Auto entering into Flower already?

If you can see pistils, she is entering "pre-flower". This does not mean she is flowering, but an indication that it is about to start. In 2-3 weeks she should start flowering properly and this is when you can start introducing "bloom" nutrients...........not now. Cannabis still needs adequate nitrogen in early flower, so keep going with "grow" nutrients until there are small budlets forming, most likely in 2-3 weeks time. If you are horrified by the fact that such a small plant has basically stopped growing and is about to divert all of its attention to growing flowers, grow photoperiod fems next time and then you can control when flowerig occurs. Autos can be rather disapponting and are not all that they are cracked up to be, they are just the latest trend and not necessarily that great. Next time, when you post any pictures, clear, close ups of the exact issue would help.........pictures taken from 3 feet away don't help in solving answers. You might know and see what you are asking about, but that does not mean that what you see can be seen on a screen by us in the cyber world.
