Hello, im growing zkittlez og auto in outdoor. But...

Stop cutting bits off the leaves. Plants can cope with at least 48 degrees Celsius outdoors in my experience......as long as they are watered properly, i.e. deeply. Be patient, plant looks great. Often the tips of the lower leaves turn yellow due to hitting the soil surface at night when the leaves are lowered. It does not affect growth rates, health, potency or yields.

Hey. So, idk but that light. Its full spectrum right? Anyways. If you using it 24hrs a day. That myth of autos taking 24hrs of light is WRONG DLI plays much more a role in autos. That's daily amount of light it gets in a 24hr period and how much par out /ppf input the area / plant has/ can take or have. Many DLI cars online..you need lux. (This can be got by getting a phototone app. Taking the lux (going by the makers max lux from its height given you then get a general strength of your light even with a phototone app as in-accurate as they are you match the lux meter to your light by doing this, using basic math) As for the heat. Your hottest part of your day make it so those 6-8hrs off are the hottest points of your day. 35c are u using an extractor. You must have one with growin. If your heat persists i suggest you add co2 to combat this amount of heat unnatural and a plant must have extra co2 to take this heat. + ppfd
