What is this leaf ๐ discolouration
Mattnanswered grow question 10 months ago
To me it looks like phosphorus deficiency. Most likely due to pH too high.

This looks like something I had before when I overwatered some of the leaf tips started dieing like that.
Best to have a bit of a dry cycle in the medium so its not so waterlogged. then anaerobic bacteria flourish and upset the dynamic sometimes cause rot or PH swings.
Good Luck!

Brown spotsWhat is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

Bottom Leaves only looking worse for wearHi, does anyone know what's causing some of my very lowest leaves to become like this? They are still attached to the plant but fall off really easily and look like they've had the life sucked out of them. The rest of the plant looks relatively fine.

Calcium deficiencyI already had a question a week ago, now it's easier to see, camera still bad.
But here are some fan leaves which I believe are showing a calcium deficiency.
Calmag is in the post, just waiting for it.
Is it for sure a calcium deficiency only? Thoughts?

Deficiency?I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? ๐ค)
The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Upward Curling Brown Leaves/Nutrient Lock Out?I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light.
Leaves are curling upward and browning. Not crumbling yet but look like they will be soon.
Both new and old growth is being effected.
Maybe the Mineralized Phosphate was too much.

Browning between leaf veins!After my low humidity problem two days ago, she seems unhappy and the growth has basically stopped. I realize it should be slowing down at this third week but these brown, dry-looking areas are showing up between some of the leaves, the ones in the center being the worst. Thanks!
