Since I don't see it on any of the other leaves just the very top ones, I have to agree with you on the light burn.

Burns on the tip of leaves
What are those burns? Are they from underfeeding or overfeeding? I was using around 1300ppm but then I decided to use 1000 and it didnt get better...

I have 2 feeds left before I start the 3 week flush. With the state of the nutrient burn, do you think I should start flush now? Or feed half usual nutes for the last 2 feeds? Her leaves will die anyway during flush so that why I'm not so well worried about the nutrient burn.

continuing nute burn or deficiency now? biobizz lightmix +organic nutes | runoffs EC 1.8-2.5 | PH 6.3 | DLI 45
cca 10d ago, I found early signs of overfertilization. I reduced nutes, but yellowing continued. After a flush 2d ago, things got worse (now also edges browning). I now suspect potassium deficiency or still nute burn. Next watering is near—should I flush again or feed properly?

brown tips on some leaves
first week of flower, only one plant out of five affected, only couple of leaves close to the top affected (up to 5 in total) - my assumption is 1. too close to light (I have 40cm between 400HPS which seems enough), PH problem or deficiency (potassium?)

problems with low leaves
in the lower part of the plant some leaves are yellowing, others are drying out and even detaching. can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.
