Banana blaze

First week bloom, very excited, managed to get a 1000 watt led growing light, I feel it's a little hot, been monitoring temperature, and it gets up to 26 degrees C and outside around 25.9 C, so just getting within limits, and I've been noticing some dots on some lower leafs, checked and no bug, don't know if it's the light switch or a kinda nutrient burn, please Info great fully appreciated.
