The lamp does seem really hot, but after spending time outside today in some of the first hot summer sun of the year, it seems to my mind that it's not much different from a hot, sunny day. I've got a thermometer in there just in the shade under the leaves and it seems to generally read between 25-28C (77-83F). The direct light seems hot, but not really much more than direct summer sunlight. I didn't have the fan down there at first, mind you, and it seemed like putting it down there helped everything immensely. A few leaves look a bit heat stressed, but they're older leaves and nearer the bottom, so I think it may be just a bit of nute burn as the top leaves seem really green and healthy. It's quite an open space, so the heat doesn't really build up, it seems.
Here's another pic from today taken under more colour balanced light and you'll see what I mean - the top near the lamp is nice and green but the bottom leaves are a bit less fresh and supple - almost a bit parched. Those bottom leaves got one light foliar feed last week and that was probably a bad idea as the next day it definitely showed a bit of nute stress/burn. I did notice that she's drinking a *lot* more water as she gets bigger. I'm having to dump almost a litre in every other day now. It is really, really green mind you, so I'm thinking I've just overdone it a touch on the ferts. It is doing a bit of the claw-leaf thing, but I remember someone (in another thread) noting that was, at least in some cases, a genetic trait. She's looking happy for now, it seems. Pure water for the next couple waterings, I think, then I plan to slowly ramp up with a bit of bloom nute as flowering starts to take off.
