Your ph should be at 5.8 for veg 6 to 6.5 for flower. Your solution temp would be best at 62 to 68 to keep roots healthy and vigorous growth. Cheers friend

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.
Maybe the Mineralized Phosphate was too much.5 years ago

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

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
