Could be a bit of moisture build up and your lights just roasted that spot slightly. I wouldn't worry unless it starts to spread or you can see it from underneath. Happy Growing!

Is this due to the sun and hot weather?
Some parts of some leaves are looking like they're burnt or something. Is this due to the sun? Or do I have another problem? It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)

Leaf damage and flower analysis
Asking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

How dark is too dark?
Are these looking too green? I’m not seeing any N-tox clawing but they are pretty dark, growth is pretty vigorous and steady though so I don’t know. They are in a pretty rich organic medium.

'rips' on leaves
Leaf damage between the veins only found it on two older leaves, had problems with calcium and magnesium deficiency early on, could this be a symptom of that or what else could it be? Haven't found any pests..

Foglie con gocce d'acqua nonostante umidità al 30%
Salve! Ho un problema (forse). Sulle foglie delle 3 gorilla 🦍 spesso trovo delle gocce d'acqua che non so davvero come spiegare dato che l'umidità è al 30% (quindi anche fin troppo bassa) e le foglie di una in particolare sembrano quelle di una pianta grassa...
