The higher the PH the more Basic the water is the lower the PH the more acidic. So if you are wanting to "lower" your PH levels then lemon juice is the way to go.
OP, do you have pictures of what the seeds looked like?

Your soil looks pretty clunky and should definitely be looked into. Testing pH is where to start, though if your pH is truly around 7.5, that's not really a problem. A transplant into a soil without so many large particles is also a good idea (try 75% good organic potting soil + 25% perlite). As a first response measure, I would stick those seedlings into a greenhouse-like environment. If at the extreme end of the temperature and humidity ranges you provided (85°F with 39% rH), that alone could be enough to dry out young seedlings that haven't established themselves, particularly those being housed in a poor growing medium.
You can build a makeshift greenhouse with anything from a large glass bowl and some plastic wrap, to a large plate, some chopsticks and tinfoil - or even just a large plastic bag! Just get an enclosed space small enough to house all of your seedlings, place moist perlite on the bottom and drape some perforated plastic wrap over the top. Mist the perlite and walls of the greenhouse as necessary in order to keep the rH between 65% and 85%. Make sure to give it some fresh air exchange at least once or twice daily.
It shouldn't take long (5 - 10 days) for the seedlings to strengthen up and begin vegetative growth when doctored in a greenhouse environment. On the lighting, you can continue to use an HID light source, but a simple fluorescent light during the seedling stage is certainly appropriate as these young plants will not use most of the light offered by the HPS until they get into their vegetative stage. The fluoro can also be kept a little closer to the young plants and won't heat up the surrounding environment as quickly since you won't need as much light intensity.
Good luck and keep us posted.

no foliar feeding. I've stopped the spraying though. I guess I got a hold of some bad intel for that one. I'll add some lemon juice slowly . Does lime juice work?

Anything acidic will work but ya I think lime juice will work.
