Leaves and buds brown on the edges

I'm about 3 weeks from harvest....growing a JockHorror auto plant in a Colorado Grow box w/2 Gal reservoir, hydroponics using distilled water. 6 100w CFL bulbs. Ph is good. Can't figure out why leave tips/bud tips are browning. Thought it might be heat burn, so I removed 2 bulbs - no change. The lower buds are looking really healthy , so I'm totally confused. Any ideas are much appreciated. Thanks!

Next time mixing nutes, be sure to add water!!

I had the same comment when I had the same issue water only for a while and the new growth if any left will look good can';t undo what has been done.

What are/were your canopy temps? Heat damage looks like it is in the mix for sure.

aww man she got burnt up , thats sum rotten ass luck . good vibes

Thanks to everyone for their opinions...nrt I did just what you suggested already - flushed for 3 days, new growth looks good. I already cut the lights from 6 100w CFL to 4......should I go to 3 or 2? Or is there something else I should be doing?

Keep your lights the same, all on.
When you start using nutrients again. Reduce them by 50% and feed.
That was nute burn. Way high N.

listen to this guy^^^^^^^

Heat stress

I don't think that's it, generally the pistils will all shrivel long before the main leaves do.
I agree with the others, 90% sure it's over-feeding, but like always, impossible to tell without looking first-hand

That does not look like heat stress to me. Unless those buds were literally 2 inches from a HID, it is nute burn.

Thanks to everyone for your help, it's much appreciated!

Maybe that's how a jock horror Autoflowers looks like considering the name? LOL
