Brown Spots on Leaves
farkel101started grow question 4 years ago
I'm getting little brown spots on my fan leaves. Growing Banana Kush photo sensitive. I think they are the result of the humidity getting too high in the early flowering stage but the spots continue weeks after I go humidity under control. Any ideas would be appreciated.

Thank you all so much. Just discovered this resource so I'll start a diary on my next grow. I'm leaning towards too much nitrogen, although I really thought I wasn't overdoing it. Despite the spots the buds are looking pretty good. Thanks again for the great feedback.

A cal/mag supplement will fix it.
I would be easing back on the nitrogen though.

I’d lean towards too much Nitrogen which inhibits the uptake of calcium.. so Nitrogen excess causing calcium deficiency.
Diary and more photos of plant as a whole would help out with a better diagnosis

Looks like calcium def. Hard to say how to fix without a diary. Could be your ph out of balance, root issues. to much of a different Nuturent causing lockout or a lack of calcium

Super thin leafs at the TopThe leaves at the top are super thin, different to the others, the leaves are also darker green, I think it has some kind of problem! It looks like I overwatered it because the leaves are drooping, but that's not the case! Can anyone tell me what the problem could be?Week 6

First grow with autos, are these growing too slowly after a week?It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week.

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 23°C / 55% humid. During night 18°C / 50% humid.
Checked the whole bud, but no insects. My other ideas are mold or stress from the light?Leaves. Color - Yellow

Does anyone know what’s going on here?Hey I have the following problem: A week ago, I bought some cuttings from a seller, but they turned out to be infested with thrips. To tackle this, I used yellow sticky traps and watered with nematodes. I also sprayed BAC Plant Vitality Plus on the leaves.

4 times same genetic but one has hanging leavesThe top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?Week 9

Weird leaf problem. Could be root?Hello community. I am currently growing three plants in the second week of outdoor flowering. I'm using the REMO Supercharger kit. One of the plants is behind the others and presented this problem on approximately 10 or 15 leaves. What could it be, a fungus or root problem?Leaves. Other

Not sure what's causing these purple leaves and leaves drying out. Plant overall seems unhealthy near the end of flowering, any suggestions appreciateThis Dos si dos Auto has been struggling over the last couple weeks with upper leaves turning purple and drying out/breaking apart. The buds also look strange to me but that may just be from my inexperience. I'm growing in organic soil and have dry amended twice, 18 days apart.Week 11

Leaves pointing upHello,
One plant has most of its leaves pointing up. Plant look healthy otherwise. PPFD is around 650/700 and light pattern is 20/4
What could be the root cause? I read mixed answers. Some say healthy plants and or strain specific other that light stress.
Regards,
