Well it cant be over ferting, because this is being grown organically (well, she gets a little bit of 5-5-10 if it hasnt rained for a while... and I mean a little, its at half strength). Light burn - again, shes outside, so she has decent ventilation!
Im guessing its the misting. Im gonna tone it down a little now, just misting once every two days and see what happens. Oh, and shes nowhere near ready, I just bought a 14x loupe from the clockmaker across the road for a fiver (bargain really, cos I had my watch fixed at the same time) and the trichs are 75% clear.

Cheers for all the input and help peeps
