Healthier than my plants lol.
Looking at your plants, it looks like the leaf burn is worse towards the bottom.
I think you can't really look past that leaf burn. Gotta fix that before any other symptoms can be judged.
The medium is too hot for them.
Most label directions should be cut in half.
I'm not sure what you'll do about the saturated soil.
Perhaps go with ph'd water in the sips for a while, until the burn stops?
If you have any genuine insect problems, I have successfully used Method1 pps in any number of situations. Small company, owners ship the product the created themselves. Natural essential oils in a formula that seems particularly effective.
Those plants aren't mortally threatened. You can bring them back into full health and get a good harvest. Just get the soil flushed and bring your ppms down.
