Looks to be a few things. Heat stress, and nutrient burn and maybe some Lockout happening. Best to use TDS pen in the future to monitor the feed solutions concentration. Good Luck

Saw this first day of 12/12
Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Should I remove parts of leaves ?
I suppose it's a something like overwatering + lamp stress. My lamp is now something like 80cm away. And I hvn't watered for 1 wk (but soil still wet, so... I wait ?). => Should I remove parts of leaves ? What about leaves with center dots? Previous question for more info, Thx

Light burn, light burn due to humidifier water lights?
What do you think caused this brown color on that leaf? I have 5 leaves like that, all the others are ok. I believe it's due to pulverizing water and droplets acting as magnifiers for the light, causing small burns. Also, since they are burnt, should I just cut them out?

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

Aeroponics system; fan leaves start browning on edge in 2nd week of bloom.
Aeroponics system that my fan leaves start browning on edge in 2nd week of bloom every time (about 7 grows in journey). Is this normal? Should i be concerned and adjust nutes at all? Or just selective trim any of the more "crispy" ones? Photo is 2nd-3rd week into bloom.

brown spots sugar leaves
I've asked this before, but the issue still seems to be there though it's very minor. Some of my more developed buds sugar leaves are showing brown markings. Last watering I flushed her but the markings seem to be spreading still, although very slowly. What am I dealing with?

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!
