Any idea what’s going on here?

Soil looks too wet. Plants displays raised leaf margins which suggests high temps or low humidity or too much wind. The yellowing of the leaf margins could be a few different things. It could be early stage potassium deficiency. A bit early to tell if it's that. To me it looks like light stress from too much light, and a soaking wet lack of oxygen in the soil scenario. Sad droopy down curled and cupped leaves suggest over water. Over water will also create necrotic spots here and there usually on lower leaves. You've not mentioned any environmental info so there's no way to know exactly what the deal is. But soil looks wet. Weed likes soil on the dry side and will be at it's healthiest and most vigorous when grown that way. Water so there is some runoff out the bottom of the pot. Don't allow the pot to sit in the runoff. And don't water again till your pot feels light. Pot feels heavy, fuck off and go watch t.v your girls don't need you. Temperature shouldn't exceed 84F unless co2 enrichment is used. Exceeding 84F without co2 your plants will stop growing and spend all their time just trying to regulate their temperature. An ideal temperature depends on strain origins geographically, but 75F is a nice temp for Indica dominant varieties. Sativa varieties are more Equatorial varieties and will like a hotter temp of around 80F For Ideal Veg VPD you want to shoot for a 0.85 to 0.95 VPD For ideal flower VPD, 1.20 to 1.50 Is what your looking for. Humidity in Veg should be 65% to 70% / 40% to 50% in flower. Low humidity and high temperature will cause rapid transpiration, which can lead to burning your plants due to the rapid uptake of nutrients. The plant just wants water to cool itself but unfortunately nutrients are also in that water and when they uptake water 4x faster than normal, they are also getting 4x the nutrient load.
