it's a % thing of phenos, the only 100% red/purples i have had so far are red poison, pure red cbd, and purple kush, everything else i have run is about 80% from sweet seeds on the reds.
My red gorilla girl XL x red poison seeds are showing even less red %, out of 10 plants in 1 pot only 1 showed red so 10% and in my 26 plant pot i culled down to 10 before the sex showed but none of them are red 7 remaining of 26 none are red lol
I dusted the 1 red pheno with red poison pollen so maybe the next round of seeds will be better with my red color i want
