Strange fan leaf markings
So I have some markings on the fan leads that I’ve never come across before. See the pics ... could this be bugs? Feed? Or a heat issue? Or is it simply mother nature , and the fact that we all have imperfections somewhere along the line?

WHAT IS THIS DISCOLOURATION? Critical Kush non auto from RQS, 10 weeks old, outdoor.
There is some discolouration on the leaves. I have removed the worst off 7 leaves and applied a pesticide for spider mites, aphids, scale insects today. Should I remove all the rest infected leaves as well to be safe? Pesticide says I can repeat in 7-10 days. thanks

There seems to be some paleness/yellowing on the upper growth. Upper leaf tips are slightly curling upwards and show some dark purple color. Last week runoff PPM was hovering around 1150-1250, so I'm dialing it down closer to 1000 ppm this week. Too much nutes or light intensity?

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)

Slight browning of upper mature leaves
Mid week 8 just noticed this color change on the ends of a few fan leaves near the top. It is only noticable on the upper most 4 mature fan leaves. Nothing on the new growth. Nothing on any lower leaves. Any ideas?

Accidentally ripped off a fan leaf ='(
Hi there, Today I was screwing around with photo seeds in rapid rooters and I moved a sticky bug trap that landed on top of my 12 day old plant and ripped a fan leaf off.. I just wanted to check with others to see if this would cause a lot of stress or stunt the auto? Thanks!

Main stem snapped
LST gone wrong. Main stem snapped after the last LST session, must have happened a while after adjusting the ties. Taped the damaged area. Will it recover? How long would it take? It looked like only 25% of the stem was holding it together. The area got red/brownish.

Sequence in the # of leaves points alterated?
I have always seen Cannabis showing a constant patter in the leaves sequence. After the cotiledona, they have first 1 point only , then 3, then 5, then 7 and so on, with Indica normally up to 7-9 and sativas up to 9+. I noticed repeating 3 pointed leaves, photo in week 6

Persistent issues - wilted leaves, light-green splotches, brown roots
My plant has these issues. I've rinsed off the roots in case it was nutrient buildup on roots, which I still believe to be the case. I have given this plant a good amount of nutrients the week before. Does this appear to be a deficiency? Any ideas? Thanks all for responding

Neon Yellow Tips?
Lemon Yellow Tips. Genetics, right? I have 4 in RDWC others don't show. Doesn't seem to be a problem. Never browns or curls. She seems happy and has done it since early childhood. I am just curious, as to what is, for future grows? Also, it may turn into a problem later?

Just wondering if it's normal for the leaves to look ruffled/wavy?
Just wondering what the ruffled looking leaves mean if anything? The leaves on this plant look ruffled/wavy, is there something wrong w it or is it just getting in it's groove to grow? Advice input opinions greatly appreciated.
