Shortryder and Whitey Tighty..Kali Skunk CFL grow...quick question

I have these 3 in a homemade bubbleponic system.....I started the shortryder just over 3 weeks ago (the larger plant), then got a few seeds about a week and a half later from a friend...these are seeds he got from bc, and I have no experience with them....my question may be more general than having to do with the strain though...Will it be ok to flower these all together, even though there is a 2 week gap in growth? Is there any way to catch up the two smaller (one of which is showing some sativa influence) plants, or to slow down the larger? Im using approximately 300W cfls, mostly 6500k, some 5000k, on a 20/4 cycle....Fox farm nutes and thats about it.....Thanks for any input, and pics are from phone, hope they're ok?

Also, one more question....is root growth rate markedly different in some strains? The roots of the shortryder are about 1 1/2 feet long, the "whitey tighty" roots are about 2"past the netpot, but the "kali skunk" roots have not breached the netpot yet, even though the vertical growth is about the same as the whitey....Could this just be normal?

Anyone????

A friend of mine is growing some tighty whitey. The plant rooted faster than anything he and I have ever seen. The flowers are kinda slower on the take off, but he was told that it will grow strong once it does.. It's a 6 week strain.

I was gonna say not to worry about it outrooting... But just noticed how old the post is.. How did it turn out??
