Brown area on leaves
Bonjours à tous. Voilà certaines feuilles de ma plante deviennent attrape des tâches brunes. J'ai donné du GHE essential (oligo-éléments) and cal magnifique (0,3ml/L) ce matin ainsi que du biographie Bloom. Je pense à une carence en magnésium et vous qu'en pensez-vous?

Deficiency/Light Stress Issues
What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

N or P deficiency?
Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Thoughts, should I be concerned?
One of my plants is developing twisted and spotted leaves. Is it just to much nutrients or something more?

Crispy brown leaves
northern light is showing yellow and brown leaves at the top and the bottom of the plant. These leaves are thin and crispy like if they are about to fall off. I am watering it 2 to 3 times per week and started adding a bit of cal mag last week when they started showing brown dots

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!

Brown Spots on Leaves
I've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.
