Hey kundal, the girls are looking healthy. Quite the lst you did there, good job. When I first looked I was thinking wtf happened to those leaves, then I realized it was the lst you did and that's why they were turned over and sideways lol Threw me for a loop there.
I am wondering if solara's issue would be a Magnesium deficiency that is causing the leaves to canoe upwards like that. If it's not a heat or light intensity issue then I think I would lean towards the Mg def. None of the other plants are having this issue so it may not be a heat or light issue. Try hanging your thermometer right at Solara's canopy horizontally and see what the temperature is right at the top of her. Where the thermometer is right now it would be a few or more degrees cooler since it is shaded down there, this would give you more of a room or soil based temperature. Also, is she the same strain as you grew last grow or is this a new one? I can't remember right off hand.
