That's normal .. With about any strain.I think you'll be fine.:thumbsup: Nice set up.. The ones that are unrooted shoulda been trimmed back of some of the leaf blades. Look good though!

I've used rockwool and love it! Very versatile, with all sizes. Gotta keep it a little more simple on the rooting solution.Use something like olivia's clone solution.Soak the cubes after being ph'd to 5.5.All ya gotta do is spray with water,use a dome,and DON"T LET THEM GET COLD!
