received new clones that are stretched, advice please

Got a few they pretty much all look like this, suppose to be a real good strain. any techniques to save these n get good yield or just grow em for couple weeks n take clones off of them?

Give em plenty of light. If you're short on light... cfl's work good for vegging at this stage it's easy using cfl's...

I got these yesterday, their under 8 bulb t5's now, I go 4 week veg but never dealt with clones this far stretched. Can I super crop the main stem lol

Think I just answered my own question, I'm thinking lst training n let the bottom shoot be the top
