Now, compared to the other one, this one has a chance of making it to the end. There are a few things I've noticed that could help, for example, your solution temperature says 90, I don't know if that's a typo or not, but otherwise, that's extremely high. Also, for flowering plants, the humidity is quite high as well; I would aim for 45 to 50% right now. As for the leaf tips, it almost looks like nutrient burn, or even overwatering.
