I had some nute burn a week or so ago. I flushed again yesterday and got my ppm (500 scale) down to 700. I’m using Coco Loco and only fed once two weeks ago. But I fed full amount of lotus nutrients which ended up burning my leaves. I was told that the Coco Loco would get me by for 4 weeks. For me, I should have waited until 6 weeks. Anyway, my Concern now is that I have a couple leaves looking worse but the rest are the same and new growth is looking better. 2 or 3 leaves have light brown spots towards the end of the leaves and several tips of the leaves are curling up. Not all leaves but the ones that had the worst nute burn. Is this do the the heat of my light ? The ones curling up the worst are on the top half of the plant. My light is at 65% and 30” away from the canopy. Could this be a combination of the nute burn and the lights being hot? I’m in 2nd or 3rd week of flower and don’t won’t to turn my light power down any more than I have to if it’s not the light causing my issue? Plant info below.

Looks like nitrogen toxicity. Dark, clawing leaves would be first indicator. The fading at the tips is also a sign of more advanced nitrogen toxicity as well.
What is your in/out pH and ppm?

I’ve been giving callas with every watering. Thanks for sharing the picture.
I did have high ppm 3500ppm about 10 days ago and got the ppm down to around 700. I’m sure I have nutrient burn but was not completely sure?
PH is 6.7 in and 6.3 out. I did a flush and my ppm was down to 700
