In regards to the water going right through the pot, stick some holes in the soil with a BBQ skewer and water SLOWLY.
In regards to the problem, the purple calyxes are normal. The scorch is from over fert- your pre-fertilized soil combined with the liquid feed is too much for the plants.
You are very close to harvest anyway so just water with plain pH'd water from here on out. If all the trichs are cloudy, you are entering your harvest window. The % amber is a matter of personal taste. Harvest at 100% cloudy for trippy buzzy, and up to about 25% amber for stuck-to-sofa style. Somewhere in between is the nice balance effect.
Nice job!
