Out door clones flowering too soon

Ok so this is my first grow, and we decided to go with clones. We ended up getting two clones from one place and about a week later one more from another place. We got them transplanted fine and they are doing great. Well about two weeks ago I noticed the two I had got first were showing the sex but within the last two weeks these girls are in full bloom. The one I got separately is only just now showing the pistils here and there. There are in the same place outside getting the same amount of light. We are now in week 7 so I figured counting back that the one started to flower about week 5-ish depending on how old they were when I got them. I have read that autos cannot be cloned so at this point I'm stumped!! Any input?

I had the same experience earlier this year . Clones are sexually mature plants that are kept under 24 hour light to stay in vegetative growth mode . As soon as they go outside they receive a shorter period of light , somewhere between 12-14 hours depending on your location , which will trigger the plants to go into flowering . My sativa dominant clones started to flower at the end of April , I had them in pots at that point and moved them on to a roof top where they received full sun all day long . It caused them to go back into vegetative state and they are growing fine now with some early flowering on the lower branches but overall solid new growth .
Apparently you have to put your clones under artificial light for 24 hours and then slowly bring down the light period to around 12- 14 hours so they can adopt to a shorter light period with out going into flowering before they go outdoor. Hope that helps .
