Check the roots. Mold ignition maybe.

Should I defoliate these bushy auto's?
These autos have grown a lot recently (on day 35 today) and are getting pretty bushy. Will this bushiness cause airflow/mold problems? I have a small oscillating fan blowing above the plants part of the day Should I defoliate anything at this point? Leave it alone?

Help, what are those weird yellow spots in late veg?
Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23Β°C / 55% humid. During night 18Β°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

My upper leaves? Is this light scald? Or a nutrient imbalance? This has been coming on over the last week. The older shaded fan leaves appear healthy. Also the one bud on the far leftside, furthest from the light is less affected. Her tent mate gets the same light and nutrients.π

Few of the older leaves have started going yellow with brown spots and shriveling up. I'm in week 7, week 3 of flower. I've been alternating nutes with Plain ph'd water, so only been adding nutes every 2nd water. Have now changed to every water. Is this just due to flowering? Ta

One weird unhealthy leaf?
I was just checking my girls when I noticed this leaf hidden away. I have no idea what it's from, so I thought I'd ask here. There was literally 1 leaf like this on the entire plant, I couldn't find another, although it's in a hard to reach spot. Any help is appreciated! π

White spots seedling
I did post before last week about some white spots on her and in the end I shrugged it off to be like nothing. I did find a little bug on the leafs and now with her grow it does seem like there might be something to the white spots... Any idea? someone had the same? Thanks!

Same strain, different color leaves.
Why my plants have leaves with different colors (one is darker) when they are the same strain? Both grew with the same fertilizers and while they had issues in early veg. they recovered but developed quite differently! It's the phenotype? Or the issues in early veg. caused this?

One of the 4 is drooping but only in the afternoon a few hours before the lights cut out. In the morning she isn't drooping anymore. Normal behavior or odd? She looks normal otherwise. Considering a flush this week. Thoughts? I'm definitely not over/underwatering.
