Did you drop water onto the leave while the light was on? that could magnify the light through the droplet and burn the leave a little. If you didn't then it could be a calcium deficiency. Check your pH first.

Maybe overwatering.
Also, since you start with small containers I wouldn't recommend clay pots, plastic is better for repotting, with clay you will damage the roots no matter what.
Happy bottanic.

Agreed-over watering issue. let soil dry out a bit more before you water next few times and should be golden.

Your not letting the roots dry out enough between watering.

November: Zu Beginn der Dunkelphase, einen Mix aus 200ml Wasser mit 2ml Neemöl, ein Schuss Rapsöl und 4ml Kaliseife, auf die Pflanze aufgetragen. Grund dafür ist ein Befall mit weißer Fliege. Alles habe ich nicht aufgetragen. Heute sehe ich schwarze Flecken. Ist das Schimmel?

Leaves are turning into dark green with a plastic-like textureI have 3 ladies in my tent. While the others looking healthy, one of them has a darker green tone with a texture like plastic and shiny. Everything is the same (fertilizer ratio, coco medium), however the one on the picture has a problem. What might be the problem folks? 😩

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.
I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light SoilOn my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Weed doctors to the rescueDay 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliageAt first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

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?

Black spots on leavesBlack 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.
