ah okok.. ic ic.. but you may have seen my plants, I keep a healthy garden. So its not deficiencies.. guaranteed, pathogens means some kind of disruptive disease or bacteria of sorts right? I doubt that strongly..
ok m8 thanks, I think we are looking at mutations here then.
There is no way 4 different strains all mutated the same way, at the same time, unless you are growing in an abandoned nuclear plant or cold war military biology lab. You are 99.99% most likely not looking at mutation. It is most likely disease, if you can rule out nutrient issues.
Genetic mutations which survive past a few cell divisions are very uncommon.
