Light stress?? Wilting leaves, shrivelled and burnt edges. See pics in last week.
Any idea what’s going on? Leaves are shriveled and wilting, as well as some burning at the edges? I’m guessing this is from light burn/stress as I’ve only watered and used very very little nuts so far. Lights were at 22 but now at 30. Temp is 24 w lights on, 55 humidity. C pics.

Lockout? Can I remedy this late in the game?
I think this is more than a K deficiency. I think I'm getting lockout. And a lot of it. She's an auto-flower, and I grow hydroponically. Can I even remedy it at this point?

What is this deficiency with DWC, GH Trio, flower day 19
I'm in about day 19 of flower and a deficiency just showed itself in the last day or so. It's in the last 3 photos of week 3 of flower in my journal. Any ideas on what it is and how I could mitigate the problem? Grow has been essentially flawless up to this point, thanks!!

Crispy dry margins on the upper leaves. Please see detailed pics through week 5 of flowering. Pics from different days are available.
The younger plant was showing what I thought to be P and K deficiencies on the leaves. Growth stopped too. Increased its nutrient amount 3 days ago (bloom-grow-acti). Since then I observed some bud growth but the problem on the upper leaves continue. Any ideas?

as you can see on some picture some leaves have burnt edges, others are 80% yellow-ish and few have yellow dots. I thought that I gave too much nutrients so I've been giving her only straight water for 8 days and more power light for 4 days. No improvement it's worse now. Please

Deficiency?
Hey everybody, I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors. Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos. Please let me know, thanks!

Browning of leaves, heat burn or pests?
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.
