i know what you are mean. my experience with thaish phenos of GT were that they can easily stop growing buds and resin when you apply higher ec or some antimold spray or something. they are very sensitive and not practicall. especially the first standart versions were bad...
but the new fem. version of zamaldelica elite selection are interesting, my are just forming buds, and by one pheno show already resin
but if you have much patience and experiences its outstanding . in very good conditions resinous like nothing in room (i compare them to ghost train haze)...
