Brown spots
Benasquellastarted grow question 5y ago
Hello team! I've got brown spots on my leaves. I've used my microscope and can't see bugs. I've been feeding about half neuts (2.5ml/L canna vega) ph is 6.5. In soil. Can't think of anything I've done.

I had a look at your diary. I'd say this might be a air circulation issue or water sitting on the leaves after watering, or leaves touching the soil. It looks like a disease more than a nutrient deficiency. Is it isolated on the lower leaves? or is it evenly distributed through the plant? I'd say its some kind of rot and I'd clip the infected leaves off and monitor to see if it spreads. If it does then it could be a soil borne disease or nutrient issue. If it doesn't then problem solved.

I think you potentially have a calcium deficiency. Try adding a little more cal mag on your next feed. Good luck bro 💪

Brown spot on leavesI'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis.
Someone could help me?

What do you think is causing the spotting, leaf curling, and stunted growth in plant #1? My money is on light burn and/or PH issue. I have a PH control kit I've been using to treat the water, but do you think just treating the water is enough? Using FoxFarm HF soil, no nutes yetWeek 2

Is this a disease caused by a lack of calcium and magnesium?I pruned these problematic leaves during the flowering period, wondering whether this would lead to a decrease in yield. Calcium and magnesium were added every time I applied fertilizer. What caused the disease? Overnutrition burn?

Cotyledon issue from seedlingHave seedlings from Auto Colorado Cookies (Dutch Passion). One already has cotyledons, but not opened yet. I see some yellow and bigger brown spot of the tip. In the beginning I had 250 PPFD, could this be the issue?
Now I am around 100 PPFD and put the light a bit up. See photo.
