From the looks of it, it looks like a leaf dying from not getting enough light which is completely normal. Hopefully, I answered your question and remember " Happy Growing".

Yellow on leaves
Day 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

Yellow spots on some leaves
I need some help guys to understand what is this? My plant leaves seem to be showing since today some yellow spots which I believe is an early cal mag defficiency sign (as I use tap water which is kind of soft apparently). Any help? Thanks in advance, my furst grow.

Light burn?
I noticed the tips of the top leaves are becoming paler, even slightly yellow. Could this be light stress/burn? My LEDs were approx. 30 cm from the canopy, now moved them up 15 cm.

Organic grow, yellow leaves, autoflower
First ever grow. I'm in my 5th week of autoflower, organic grow. Using the bomb paonia soil, raging kush light and boogie brew tea and filter to water. Temps are steady around 86. Started noticing yellowing on bottom leaves. I'm pretty sure it's from under watering? any feedback?

Should I cut some fan leaves?
Hi and TIA, my plant is finishing week 5 of flower and I'm seeing some of the old fan leaves are turning yellow, so I wonder if it's a good idea to cut them or should I leave them alone?

Anybody got any idea with what's going on with these 2? The 2 larger plants are showing the signs of some stress on the fan leaves. Oddly enough the runt of the 3 is not showing these signs. Has anyone seen this before or can help me identify it?

Not enough nutrients for Nirvana Maui Waui in light soil?
I have overfed my last grow by spraying it with Alg-A-Mic... so this time around I kept giving her only a minimum of nutrients. Looking at the yellow leaves and the brown spots... most of the leaves touched the tent... am I UNDERfeeding her now?

IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak
