ello perp.. i would say that my plant looks very similar to the pic under phosphorus deficiency in flowering... but my plants is in the veg stage.. but it has shown sex.. i am using mother earth veg ferts .. but i have only gave the sick plant 1 very small dose of it.. the sick plant was in too rich soil from birth which hurt her.. then i repotted into multi purpose compost got some improvment but still the brownin dying of the leaves.. but recently i repotted her into her final home .. using bio bizz light mix and a touch of bio bizz all mix at the bottom for when the roots reach down there.. allso added quite a bit of extra perlite for better drainage..
