Leaf Septoria?

Recommended Posts

Hey guys new here on the forum been lurking around now for about month and now im in need of some advice if anyone can chime in.


My white widow x big bud are looking a bit on the unhealthy side, to me it looks like leaf septoria but im unsure?? A bit of history, in there 1st week of veg we had some cold nights, I noticed droopy leaves some purpleing on the edges and dark spots on the leaves so i got a heater quick smart. About a week on with constant temps sitting at 25-27 C the spots are still appearing and seem to be getting worse.


If any experts can point me in the right direction it would much appreciated.

Cheers everyone! :thumbsup:
