Been reading back, good grow! looks like youve got good help but i'll chip in anyway! your plant does look like the sativa-y kind, from the stretch and the leaves, leaves that thin should be able to handle more heat than wide indica dominant leaves though, otherwise id of though they'd be burnin by now that close to the hid, unless i'm not seeing a cool tube? dont listen to the idea of not using sativa in scrog, it reckon it might be the best way if you have little space and want that kind of high, i havent scrogged a sativa myself but the principles must be almost the same, probably cover your screen with one big monster!
good luck with it ill keep watching!
