Yellow leaf tips and edges
crusoestarted grow question 5y ago
Hi I've got a problem that I've seen from the start of my grow and it's getting worse on older leaves now - zoom in edges and tips are turning yellow. I thought it was magnesium so I've dosed with Calmag but it's not improved - I'm Ph6.5 - any ideas?

Hi mate, by the way the leaf edges are curling up I would say it is light burn. Maybe lower the intensity of your light or raise it up a few inches till you see improvement. At this stage they don't need full sunlight. around 250 - 400 PAR is perfect. I hope this helps, good luck and happy growing

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Wilting leaves and copper spots? Save Me!These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

IMPORTANT excess/deficiency? What's happening? Flowering is in dangerWhat's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Leaves full of brown spotsMy friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

Plants deteriorating rapidly, pls helpPlants not looking good! Help!
White tips at the end. Brown patches. Leaves curling.
I've been feeding it 0.5L Advanced Nutrients Coco Big Buds.
The light was fairly close, at 30cm. I've raised the lights to 60cm.
It was also very humid, so I've opened the air vents .

Plant issues... How long to harvest?Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!
