First Grow, First Post

I've been growing five plants of different strains, same age yet significantly different sizes. If anyone can tell me whethere they are sativa or indica that would be cool. I used miracle gro 20-20-20 powder for the veg and now i've switched to miracle gro bloom booster(15-30-15). They've been flowering for about 4 weeks.

I took clones about 2 weeks ago and they still haven't rooted. Is it because I cloned during flowering? I used olivia's cloning gel and misted them with olivia's cloning solution for the first week and now i've switched to nute-less water. They're in 24 hour light. If anyone could has any tips it would be much appreciated.
