Fungus or deficiency?
jbirdsthewordstarted grow question 4 years ago
I have these gals growing outdoors and have a few leaves that look like this. Appeared after multiple heavy rain days. Applied nutrients yesterday so I still need to wait for the results. Is this a sign of fungus or deficiency?

It was bugs. Both times I’ve asked a question and mention that I’ve been adding calmag the majority of responses are calcium deficiency. It wasn’t, both times.
Thrips and other flies that were taken care of with neem oil and soap.

It’s a calcium deficiency.
There’s many reasons for a calcium deficiency. The problem with the evapotranspiration can be caused by an excessively high EC value of the substrate or by excessively high or low relative humidity.

I’ve been adding a nutrient mix, by bud juice called micro. It has calcium and mag in it. Plus the water here has 50ppm Ca. But that all may not be enough. Will try CalMag tonight and we shall see.
Repotting tomorrow or Wednesday, waiting on the gals to take in their latest feeding before the move.

Looks like you got nutrients on the leaves in those spots.

Looks a bit like calcium deficiency, or slight one. Plus your plants need potting up.

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?Leaves. Color - Dark-brown

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.5 years ago

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.Leaves. Curl down

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? 🤔)

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.

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!Week 10
