My plants need a diagnosis please!!
after some tops got burnt by light, many lower leaves began to turn yellow and have crispy tips. I was not sure it's a nuteburn or deficiency, but more like nuteburn to me, so I flushed soil yesterday and had a bit water sprayed on plants during the process, after that, my plants turned withered.
So, deficiency or nuteburn?? and what happened after they had that shower?

Guide for Diagnosing Plant Problems
I came across this neat little list that can probably help a lot of people out. If you like it check my post in the General area...I need some help!

Quick Deficiency Guide

Nitrogen: Entire plant is light green in color; lower leaves are yellow; growth is stunted....

Phosphorous: Entire plant is bluish-green, often developing a red or purpleish cast; lower leaves may be yellow, drying to a greenish-brown to black color; growth may be stunted...

Potassium: Leaves have a papery appearance; dead areas along the edges of leaves; growth is stunted...

Magnesium: Lower leaves turn yellow along the tips and margin and between the veins; the lower leaves wilt...

Calcium: Young stems and new leaves die...

Zinc: Leaf tissue between the veins is lighter in color; yellowed; papery in appearance...

Iron: Leaf tissue appears yellow, while the veins remain green...

Copper: Leaf edges appear dark green or blue; leaf edges curl upward; young leaves permanently wilt...

Sulfur: Young leaves turn pale green, while the older leaves remain green; plant is stunted and spindly...

Mananese: Growth is stunted; lower leaves have a checkered pattern of yellow and green...

Molybdenum: Leaves are stunted, pale green, and malformed...

Boron: Young leaves are scorched at tips and margins...​

the soil ph is around 6.8 and the runoff is 6.4. I did not mean to spray em and I waited like 2.5 hours to let dry before I turned on the light. IDK, maybe they were not completely dried.
