Running a photoperiod strain, currently at day 35 of flower. Lower and mid-canopy leaves are yellowing pretty uniformly, starting from the tips and working inward. pH is dialed at 6.1, runoff matches.
Week 7 of flower and my fan leaves are turning deep purple. Nighttime temps are around 60°F. Is this a problem or just fall colors? The buds look healthy.
Seeing brown spots AND yellow tips at the same time. Some leaves have burnt tips (nutrient burn?) but others are yellowing from the bottom (deficiency?). How can both happen at once? Running coco with
Running DWC hydro and my pH drops from 5.8 to 4.5 within 24 hours. Constantly adjusting. Using General Hydro pH Up but it won't stay. What's causing this?
Running coco and getting brown rust-colored spots all over mid-canopy leaves. Looks like calcium deficiency from what I've googled. Already adding CalMag at 2ml/gallon. Not enough?
My fan leaves are curling downward like eagle claws. The leaves are also very dark green, almost black-green. Currently feeding full strength General Hydroponics Flora series. Is this nitrogen toxicit
Transplanted from solo cup to 3 gallon pot 5 days ago. Plant hasn't grown at all since. Leaves look OK but zero new growth. Did I damage the roots?
Checked my soil runoff and pH is at 5.0. Input has been 6.5. Plant is showing multiple deficiency symptoms. How do I raise the soil pH back to normal range quickly without shocking the plant?
Doing a routine check and found gray fuzzy mold inside my biggest cola. The bud was brown and mushy inside. Is the rest of the plant safe? Should I harvest everything now?
Pulled my net pot to check roots and they're brown and slimy instead of white. Reservoir water smells bad. Plant is wilting despite being in water. This is root rot right? Can I save the plant?
Dried my harvest for 5 days (stems snapped) and now it smells like hay/grass instead of cannabis. What happened? The buds looked and smelled great on the plant. Can curing fix this?
Found banana-shaped growths (nanners) on one of my 4 plants in week 6 of flower. The others look fine. Do I remove just the bananas? Remove the whole plant? Will it pollinate the others?
My autoflower is 5 weeks old but looks like a 2-week-old plant. Only about 6 inches tall with minimal branching. Already showing pre-flowers. Did I stunt it? What went wrong?
Found hundreds of tiny green aphids all over my outdoor plants. They're in early flower so I don't want to spray anything harsh. What organic treatments work without affecting bud quality?
Found white powdery patches on several fan leaves this morning. Pretty sure it's powdery mildew. Plant is in week 3 of flower. Is my crop ruined? Can I still save it? What should I spray in flower??
Week 5 of flower and I'm seeing brown spots appearing on fan leaves in the middle of the canopy. They start as small dots and spread outward. The edges of some leaves are also getting crispy. Running
My leaves are curling up along the edges, making them look like taco shells. The tent temperature is around 85°F with the lights on. Is this heat stress? How do I fix it without buying an AC unit?
Every time I water my plants, they droop for like 24 hours afterward. They look healthy otherwise — green leaves, growing well. But the drooping after watering is concerning. Am I using too much wate
There are tiny black flies buzzing around the soil surface of my plants. They're really small and seem to hang out near the top of the soil. I think they might be fungus gnats? Are they harmful? How
Top leaves are yellowing/bleaching but the plant isn't wilting or drooping. Tent temp is 78°F which seems fine. Light is a 300W LED at 12 inches. Is this light burn or something else?
