No it will not lose a set of chromosomes. Polyploid plants grow and kinda look retarded. They have big everything and will twist and kinda look irregular. Its alot like down syndrome in humans. Well thats probably what happened. If not, then i don't know. There isn't much study on polyploidy in cannabis. I have a triploid in my first 10 of the year. I wonder, if you've done breeding. If you have lets talk. [email protected]
