The ambient temp looks on the high side for sure but ok. 85ºF ambient in the enclosure is the upper range but ok. so 84-86º ambient you stated. I am guessing it cools some over night? Is this normal temps or just a high point. If it is a high point I would keep an eye on the temps perhaps try one of the 'swamp cooler suggestions (ice and fan of some sort) and let it be. If the ambient temps hit much over 88 I'd stop feeding. Humidly is not an issue unless it is coupled with stagnant air. Bacteria grow best in warm humid and closed conditions. That is why ventilation is important.
