Hey red, so i did a strawberry cough this year too and her leaves were definitely the more long fingered skinny leaves. I see the additional light added, thats some seriously good strong wide coverage they must get, did you notice a shift with adding more light? If so you could remove until a little further on, or possibly raise the light slightly, maybe up to 18 inches. I know checking the manufacturer's suggestions are always helpful, just to make sure were in the good zone.
Happy growing, i cant wait to see the end of these strawberries. ❤️🍓✌️
