If the ambient temp is 79 - I would be worried about the reservoir temps. This can be the downfall of DWC. You really gotta dial in the best spot between your solution temp and ambient temps of the room.. Too warm of a nute solution will cause issues quick. Just something to keep in mind. Also, I’d pull that pH down below 6 - when I run DWC I try and sit at 5.7-5.9 at this point. No idea on your genetics (photo or auto) but assuming your PPM is 500 scale - this is an EC around 1.0 which might be a bit much for some varieties at this early stage
