Need Help...Preflower Clones

I've succesfully cloned a plant 3 weeks into flower I wouldn't worry at all, just veg em clone em and flower em

Yea I'll see how it goes and probably gonna get some more clones just for safety. Last year bought some clones preflowered and didn't know so I had it under the light 18/6 for few weeks and then I put them in the ground and they flowered early and it grows and stops and only one leaf was showing then 3 and those plants suppose to be monsters and they were like 6 feet tall only and the yield sucks because it bud stop and bud again and I only got like 1lb out of those 6 plants.. 1lb out of 6 6 feet tall plants........
