Burned or finishing early?So I'm very torn about what's going on with my Jack 47 Auto. There's part of me that feels I may have burned her, and another part that thinks she's just finishing early. I have details in the diary. Any insight about what I did "wrong" would be great!4y ago

Dark dots in leaves. Lamp burns?I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.Leaves. Curl up

Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!Week 4

Does this look like minor leaf burn, too many nutrients or something else?I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.5y ago

Weird Spots on almost every leaf overnight? (Leaf Burn???) My plant developed these spots on the leaves basically overnight...I was looking after them just yesterday evening and the plant was fine, however I did a mistake.
The left plant got completely wet (i had to move it through the rain) and i did not dry it before the light went back on.
Right plant is completely fine.

Hello GD friends. My little Diesel Automatic is showing some odd mosaic'esque coloring on the baby leaves. I'm inclined to just let it go for now and see what happens. But if there are any suggestions on helping her out, please let me know! Thanks!Week 3

Third grow. My plant started making brown spots one week ago. Today, the problem continues. I feed my plant with Pelargon Terra Bloom, sometimes add Pelargon PK13-14. I don't control ph level, but previous two plants don't have this problem.Leaves. Color - Mottling

What's the issue with this leaf?Can anyone help identify the issue on this leaf. Dreamcatcher is the strain and I can tell they were a reveg. It was root bound and I thought it was an issue with the roots. After transplant outside and sprayed with my IPM the plant has recovered but still has a few like this?Week 14
