Light burn on Purple Haze Autos? with pics

Its my second crop so I'm still pretty new at indoor growing, but I have a Purple Haze Auto that's approximately 8.5 weeks from sprouting and just over 5 weeks into flowering

I have the 1 girl under 2 amazon special 1000w led lights. Actual total draw is 110w for each.

I did an all natural soil, but started light on the Humboldt flower stacker 3 weeks into flowering; however, I noticed the burn shortly before that.

Water ph is good, temp has been mid to high 70's with the lights on.

Please let me know if I have a problem using 2 lights. Thanks in advance.

This was nute burn, not light burn

Really? Ouch! Was only 1ml per gallon. I figured it was light burn, because I had the lights around 18" off of the highest bud.

Nute burn... you're not gonna like that bud... when I did the same, had to toss my plant, couldn't smoke it...

Nute burn doesn't mean your bud will for sure be terrible, but it is another stress factor to avoid, I would go with 50% of that dose.

Ugggh here's another issue I just found. Probably related to the nute burn. Looks like the bud was dying and started to rot.

Oh I've since stopped using the flower stacker and went back to straight water. Hopefully I can flush it out. Looks like flowers are growing better now aside from the one I had to clip.
