No pics no help

I am also growing HGK at the moment. They need to be super cropped if growing indoors because they are quite a tall plant.
Sounds like you either have low humidity, your HPS too close, or a nute problem.

Pics, what youre growing in, what nutes are you feeding?

To many cooks in the broth, leave to only one partbner to feed and care for the plants, treat for nute burn ..Flush with 3 times the volume of the pot, with air temperate Ph neutral water, allow to recover in dim light, one day or overnight......avoid feeding for 2 weeks then resume at half the current rate only resume, when you see a positive improvement
