Of course... Forgot about organic. Silly me 
I don't use any bottled nutes with salts in them, so there's no point. Over saturating the soil can cause PH fluctuation as well. I would only flush if I had too much of a buildup of nutes, which doesn't seem to be your problem. Can you tell us the exact ph of both your soil and your feed?
I hear ya. Some folk still be shocked when I go to roll a spliff and theyre all "You can skin up!... N ur a girl!" I'm 26 and I've been smoking weed f almost a decade. Be hard t do that if I didn't. Never get suspected of doin owt dodgy though which is a cheeky bonus![]()

sooo...im in the US so in layman's terms this- " Never get suspected of doin owt dodgy though which is a cheeky bonus" meeaaannnsss.....what? lol
Im also assuming 'skin up' means to roll. And under that assumption, lol, Im 27 been smoking OVER a decade, and I cant roll to save my life hahah. Ironically though, my younger brother can roll a damn good blunt and my dad can roll the perfect joint. And I mean, perfectly round like a cigarette, perfect doob haha. Musta skipped me![]()
Have you tried foliar feeding? I'm having low PH issues at the mo and she seemed t stop growing but been spraying her the last couple o days and she's beasting it again. Must of grown about 3 inches overnight :-D
