I have to agree and disagree.
If you treat all plants the same, yeah some are going to hermie because all plants are different and need to be treated differently.
If you are feeding your skunk plant the same as you are feeding your haze plant, your haze is going to be a freaking mess and vice versa. That can easily cause plants to hermie that, under different circumstances, would not have hermied. I do everything I can to NOT be the cause, i.e. light leaks, feeding, watering, training, and if it hermies it is most likely genetic. But from my experiences it is usually the grower not understanding the requirements of a certain plant. I am not saying in all cases, but in most cases.
So just because a growing technique works WONDERS with one pheno of a strain, doesnt mean it will work the same with other phenos or other strains.
