Black spots on leaves
longearringboy420started grow question a month ago
Black spots present on some fan leaves. During ~3rd month right now. Watering with HESI in Coco Coir, PH ~6 every time, 1/2 runoff water.
For about 2 weeks prior to this, I also added very small amount of kelp powder.
Soil seems fine.

Plants look overfed in general. They are also looking like they are fox tailing. this could be from excess heat/light and low airflow. some plants do this on their own though. I do some light stress on them as well. their is bleached tips in one of the pics and lots of crispy sugar leaves. you should try and find your DLI you giving them or just dial back the light a bit from 100% to 80% or raising it more if its possible.
Honestly the plants are close to being done and its huge for the tiny space it is in. I don't think I would worry so much about this and just finish it off.
I am curious how this turns out. Hopefully you'll start a diary on your next grow.
Good Luck!

I'm not sure my friend but it looks like something external, nothing wrong with the plant or roots.
I would consider some alphids or something like that, it looks like some dots and not a spot, maybe eggs or very small fleas. You tried cleaning them?
Sure you gotta keep an eye on that and i wish I could help more, beautiful girl you have!
Happy growing!

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance.
Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

Gray leaves on buds with a massive concentration of trichomes. What is it?No clue what this is. Light gray leaves, tons of trichomes. I'm a bit confused here. Should I just cut the buds that look like this to be safe? Or is this normal?
