Copied and pasted from that dude talking about polyploid;
Polyploid Traits:
Ducksfoot
Four sets of leaves at the nodes
Stretched (doubled) flowers
Dark green leaves
Double bud sites
Heavy feeder
High water consumption
Thick meristem
Pistil discoloration (pink pistils under black light)
Extreme potency
Crooked looking plant providing a Bonsai appearance
Larger stomata
Thicker leaves
NOTE: In order to correctly determine a polyploid level you must extract DNA from the root stain the sample (several methods), put under microscope, count the gametes surrounding the nuclei. You must draw what you see in the microscope and then count. As cannabis has 10 gametes, the number should be 20 for 2n (normal diploid), 40 for 4n (tetraploid), 30 for 3n (triploid), and 60 (hexaploid) for 6n and 80 for 8n (octoploid).
