She's had a good week given the issues some of the other girls have had, the leaves look a little burnt, possibly down to a foliar spray used on a bigger girl that may have strayed. There's also a slight bit of windburn starting to show on one of the leaves so I've adjusted the intake pipe and rear fans a little to try and stop any further issue.
The loft is getting warm in the daytime, around 85f which isn't too bad for now but I think I'll have to come up with a makeshift cooler to hook into the intake pipes before too long, certainly before harvest as that's going to be in the loft too.
I have a week or so to decide on training now and what methods I'll use with her.
