no they look ok ,apart from a few slight yellow leaf tips ,few odd dots hear there nothing to worried about,
got incoming air + big osculating fan + extractor fan ,I keep dumidifier off at day time have it on all night time only .
like you say ,good idea to switch light cycle on at night time .off in day .
what's it do to buds ,HOT TEMPS ? or can the plant tolerate some warm spells .
