Bad genetics? black afghan

A question from a fellow grower;

I’m having problems with a strain. Its black afghan. These are clones that we got off the previous grow. We five different strains going, including white widow, pinapple express, and a mystery. I’ve been growing these strains for a while and they are all phenomenal plants. But I’ve never ran across this. I’ve only been growing for a couple years and so far so good. I’m just wondering if I’m wasting my time on these. Thanx.

No grow it - and learn from it - all plants develop differently as you know = it’s nothing you did wrong !
