tips turning brown
jimmyboystarted grow question 5 years ago
I have 4 plants around 8 weeks old and I'm noticing the tips of some of the leaves are turning brown. What is the cause and how do I correct it before it gets worse?

there's definitely new growth. They started flowering almost a week ago. I haven't watered them since Sunday and I think they are recovering. I don't see it spreading or getting worse.
I mixed the three nutrients that I have together and watered them i think that did it.

No picture at all? Hard to guess then. Nute burn.

Could be a few things.. Under/Overwatering, nutrient deficiency, or light burn.. Is it on old and new growth? Is there any curling? Brown sports or yellow leaves?

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistilsSo this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.Buds. Not fattening

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad5 years ago

Browning of leaves, heat burn or pests?Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.Leaves. Edges burnt
