If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

Is this light burn?
All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance

Mängel von Pflanze #3
In der Woche 5 hab ich Mängel bei einer meiner Pflanze entdeck und versucht diese zu fixen, leider ohne Erfolg, wie man auf dem Bildern sieht. Was könnte ich das nächste mal anders machen um das zu vermeiden? Bzw jetzt schon für meine letzte Pflanze die noch keine Mängel zeigt.

Is it possible that maybe I underfed my plant and that's causing my actual problem? Is it something normal? Or there's something else going on with it that I should check and fix fast? In general the plant has a lighter green color and old leaves are getting yellow. Thanks!

Purple leaves getting worse!?
So I started getting light purple/yellowing last week, after my last grow question, I landed on potassium deficiency. I gave a healthy dose (2 tbsp in a half gallon of spring water) of Fox farms big bloom (0-.05-.07), within the last 48 hrs and the purple looks worse? Any ideas?

Newer growth is lighter in color and thicker than the other leaves. She was under my humidifier so maybe drinking too much? Dry organic amendments so no additives in water. Several other grows in same feed schedule and no issues

Nutrient lockout?
Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!
