Hey mand, hmm I cant really help you with the rusty leaves... although I have had something that looked similar on Fiona, and a quick water with some Epsom salts cleared it up. You can get them from any chemist (I dont think a Tesco/Sainsburys etc chemist would do them though) for a couple of quid, and its quite a large tub. They clear up constipation aswell, if that interests you
Anyway, Ive been thinking about leaving the males in with the female Lows because I wanna stockpile some seeds up... and if I manage to get some males and females outta this grow, would you like some seeds? The potency wont be anything like that of... er... whatever strain it is youre growing now, but its a fun dinky little plant. Also gives you the opportunity to make some crosses if you want, although LR crosses do have a tendency to turn hermie pretty easily...
Anyways, just say if youre interested in some seeds and Ill pop some in the post when they develop. Dont worry about p+p, ittl be all of 50 pence anyway!
Good luck with the grow, although I really dont think you need it... and about the toyboy idea, what about the old man with the camera fetish?
