First time grower. Thought I’d help get things going here. Pretty sure I have some mute burn here but thought maybe other could chime in. Northern Lights Auto. Organic Soil. Water PH 6.5. Gave first dose of nutes 4 days ago at half dose. Figured it was time since the first leaves started to brown.
Other thoughts are it could be overwatering or maybe light is too close or bright. But neither seem right since I wait for soil to dry to water and following guide my light came with.
Any thoughts?? Thanks
Seedlings need less watering and more humidity, try to make a humidity dome, or cover with a ziplock. If you can dem lights, try like 20%. There are a few apps that will use your front camera to read the ppfd of your light intensity.
Also. Apologies. Forgot to include humidity in my description. Currently sits between 60-70% in the tent.
You should probably still have a dome over seedlings
This is new info to me. Can I ask why? My understanding is the dome was only for humidity levels.
Yes that's true, however the humidity in your tent is spread throughout. As to where if you have a humidity dome, the humidity is closer to the plant and your seedling will soak up some of that moisture through its leaves. Giving little sips of water. During the seedling stage your roots need a lot of oxygen, so if you're overwatering you can easily drown your roots, thus seedlings issues.
Yeah this is what I think the issue is too, overwatering is keeping oxygen from getting to the roots and preventing nutrient uptake, hence the white/yellow leaves at the bottom of the plant
