Yes And gt…psychoactivity… Not something extra. I Just like how some thais resin But i Dont to grow them. Ive " selected "11 beans of Early Malawi way of selection And was terrible 
Just one pheno of 7females cca 50thai/50Malawi was hardhitting And strong.
Thai phenos háve Vigor And r pretty resistant to everything, But when you add bit more fert not good or you spray them, the buds are developing slowly. Than two weeks good And you say whoo it resins good. Than another disbalance And… Much patientce needed… No need to go ať highly ec - 0,6, 0,8 max in peak And all organic…
2)Malawi phenos are Also not extra Till you háve the killer pheno. Moderate ec. I have experiences that at mineral Feeding she didnt developed buds easy ať First round with Wild seeds. Sucks.
And the effect of gt was quite good But in my hands above average, Notting trippy really…
Together i wasnt satisfied with gt
Zamal x malawi killer was another story. Best…And Also trippy And other phenos can be found. Dubi Wrote ať zamaldelica thread detaily of breeding
