If you throw them into bud during a reveg with funny leaves, they make funny buds. The plant is confused.
This year we had a big problem. I made a cross about 5 or 6 years ago. I've done about 175 to 200 crosses so far, but this one is my favorite. I never released it. My son, exwife and I keep it.my sons plant wouldn't clone this year, and my ex lost hers while she was working in humboldt. I had to take my one copy that was budding outdoors, pull it inside. It's a mess. I will use it for a mother. I always bud them much later when they return to about normal, otherwise I'll get a bunch of weird popcorn shit.
Find me a good one and you're off the hook.
