Brown Spots, Any Ideas?
AutoCannabisCultivator123started grow question 4 years ago
Anyone know what is causing the brown spots on the leaves? So far it’s limited to one plant, and it was closest to grow light. PH of soil appears to be normal, and I have not fed any nutrients yet. The water in my house is treated with Calcite/Corosex for PH correction.

Brown spots are usually a cal mag underfeed. though this can be something different try upping her feed abit keeping the ph between 6.5 to 7.5 when growing in soil. Though it does look like a cal mag issue to me. great looking grow keep up the good work :)

Do you mist your plants with a spray bottle? They say the light magnified through the water droplets can lead to burn spots like those. Could possibly be fungus knats, do you see any tiny bugs flying around your plant or your soil? comb your fingers through the top inch of your soil, you should see little bugs fly out if you have knats. If you do have them, simply watering less often should get rid of them. If not, using Diatomacous Earth(you spread it over your dirt) helps to kill knats and their larvae they leave in the soil. It also could possibly be a lil bit of nute burn if other leaves show brown spots on the tips.

Are rust spots a concern for harvest?Hi! Rust spots appearing on fan leaves - Week 9 Autoflower - 5th week of flower. I'm hesitant to add anything to the soil so close to harvest. I'm using Gaia Green Organic dry amendments. Is this normal and part of 'fade' process? Will this damage yield or potency? 6.3PH

What is the problem?Hey, plant is pretty fine and I guess I harvest at day 63 flo.Anyway during the last 2 weeks I saw this issue on leaves. To be honest I ignored the problem, buds were and are getting bigger without trouble and I was messed up in my personal life. But I'm curious, what causes it?

First flowering? - is it the right time? Also, 'claws' on the tip freshest leavesIs this a first flower on BPP? I have no idea when to start with Bloom/Topmax, is this the right moment for this plant?
Also, you can see the little 'claws' at the tip of freshest leaves, just on top. Is this caused by putting the light source too close? It was 40cm,now 47/18,5

Almost two weeks old, got her first spot on a leafWhat do you guys think is the cause of this? She is only 13 days old. Is it a light burn? She's getting 16-20 DLI until she develops more leaves. Wind? I'm not giving any nuts yet. Even her last water was like a week ago because her soil still feels a bit moist. VPD Early Veg.😽

Leaf issuesThoughts on the cause of this? Planted in ground. Rainwater only. Compost has been the main nutrients.A small amount of 0-30-50 booster powder has been used. Other plants are not as bad and the middle plant has no issues. All approx 2 weeks into flower.
