It looks to be both, the existing damage got worse and it spread to more of the plant. I actually don't think it is bugs any more. I think it is nute lock. Lights are off right now so I have to wait about 1/2 hr. But last night all the new growth looks to be shriveling up. I used straight water from the dehumidifier yesterday so I hope it looks better today, but I think I may need to flush more. I'll get new pics as soon as the lights come on.
