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?

White leaf tips
Any idea what can cause these white/light yellow leaf tips, mostly on the newest leafs?? Might be light burn, it’s quit a powerful led (niello m-900) or maybe high on nutrients?

Noticed some brown tips showing up. . I've never fed at 100% full strength yet. Is it still to much or a deficiency you think?

All of my plants have started to burn yellow in colour when they switched to flower, they have also lost they lovely green colour and started to go lime. Too much nitrogren still in the soil? Or Just a deficiency? They have recently been fed 1ML fishmix and 2ML Bloom.

My Green Poison leaf tips are burning not sure what it cld be. I was thinking magnesium deficiency jus off the simple fact that I have been using distilled water which doesn’t have any nutes the plant need (now using de chlorinated tap water) or is it heat stress or nutrient burn ?? I know my tent can get a little hot because of where I’m at but it’s somewhat under control. But if u have idea or suggestions for my Green Poison I’d appreciate it .

Why does my bottom leaf have brownish white tip and is cripsy?
Was checking leaf temps all over and at the very bottom first 3 point fan leaf that she ever grew I noticed the center leaf crispy at the tip with some light green spots around it. The only other leaves that look like this are the single first true leaves. Thoughts?

Yellowish color at the tips and wrinkles
My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.
