For a first timer, your photo looks like a set-shot from a magazine, I believe your plants are doing fine, you've had these clones for awhile then? Also with clones you'd think you could tell the sexes by now (people usually dont clone unsexed plants from what I hear). Finally, losing one out of it looks like 8 or 9 is very good, especially at their size.

you a re doing just fine from the looks, please, continue on...
