Looks like natural leave colours to me, don’t worry too much just keep an eye on it. Leaves are prone to develop mutations

My plant has mass nutrient burn on most of the leaves, I've flushed the roots. Is there anything else that can be done to help recovery or is it to late in flower. Also should I remove all the effected leaves or will they still convert energy for the plant? Thanks

In the 4th picture of week 4 I have pictured some leaf damage occuring on relatively new growth. From what I can google this appears to be a potassium deficiency, any opinions?

Heatlight stress?
Can someone tell, are these brownish tips the sign of the heat stress or something else? And how bad is that for the plant's not so distant future? She grows indoors. Peak DLI was almost 60 but very briefly about one night. Now it's dimmed to 40dli/~600ppfd/ 20/4 schedule.

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?
Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening

Burnt looking seedling
What's going on with my #2 seedling? I thought it could be light burn and raised my light by 4" but the odd coloration on the tips has gotten worse 18hr later. It also doesn't seem to be drinking whats in the coco yet so I'm cautious about feeding.

Can anyone help identify this tox/deficiency?
Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

What's wrong with lemon cheese? Is it overfed? Drain showed me 800 ppm and after flawless finish drain became 600ppm. Or is it my tap water (300-400ppm WITH FILTER)? Should i get reverse osmosis?

Do you think the yellowish leaves are because of nutrient deficiency, a nutrient burn, or just her fall colors?
