Black spots on leaves
Trickotreat47started grow question 2y ago
So I have those black spots on leaves on top of the canopy of my plants. Can someone please explain what are those and how can I treat it? Also the edges of the leaves on top of the canopy are brown and crispy.

The burnt tips are a nutrition/pH issue.
The black blotches could be a fungal problem due to poor air exchange/high humidity.

Deficiencies while in late flowering during flushing periodThere is deficiency going on (looks like cal) she is an auto flowering strain in her 9th week and been flushed for a week now. Should I give her cal/mag and stop the flushing or is it too late to deal with that? She looks like she will be ready to chop in a week or so.

Brown spots on older fan leavesSpotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be?
Does not rub off- was worried about rust at first.
Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.

Brown spots new leaves - floweringBrown spots on the canopy and leaves are less greener. I suspect it is Calcium deficiency caused by a acid Ph (my Ph meter was not calibrated). I have flushed it and fed it normally 5 days after the first signals. Is it really Calcium def or another thing I'm missing?Week 12
