Is this a phosphorus deficiency? I've upped the feed a week ago but it's not improving yet.

I also reckon that's calcium. Something to consider, most calmag supplements are biased to the magnesium side (typically around 2 to 4:1 calcium vs magnesium, which is often a bit high for magnesium, but situational).

Calcium problem mate I would say. Up your calmag 1ml 1lt or use 0.4 as a base for you feeds. Do not flush if in coco the soil needs nutrients and you will not help it 👍🏻 feed twice a day with run off until problem sorted 👍🏻❤️🌱🍁 happy growing

Problem came back Hey mates, sup? This week the problem is back, milder than last week but still here. I haven't added anything to the soil yet and I'm worried about it. What do you think it should be? Overfeeding, magnesium, light?

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.

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? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

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!
