hey all.
bit of an update for ya:
sexed the little buggers now and only 2 males out of 7 so that is good. Was still difficult to cut them down though, had to force myself to do it knowing that it would be stupid to leave them up. as this is my first proper grow (have done a couple of greenhouse grows before but never got amazing results) i am taking photos of everything!

my mystery problem is getting worse slowly. I am now using water with a ph of roughly 6.8-7 to try and not get nuet lockout but it seems like i am still getting it. The tops of the plants are looking fine but i am worried now that it doesnt seem to be getting any better and a few spots r appearing on the next set of leaves up and the bottom leaves r pretty much dead! please guys, grower on knees here: what is it!? and how do i sort it out before it kills my plants!!?

here r soome pics anyway
