Hey, these are signs of calmag deficiency, these brown spots are the main symptom. Add some calmag and you’ll be okay 😊

500 or 700 ppm ? 500 is a bit low, 700-750 ppm (NaCl 0.5 scale) should be fine

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?

Should I cut these off ?
leaves are no longer crispy and dry but are still rapidly changing colour, not sure if I should cut them off or let them fall off themselves ? if I cut them off would it be beneficial ? not sure if the plants still putting in energy to keep these leaves on the plant or not ?

Brown spot on leaves
I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis. Someone could help me?

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?

Brown spots, serrated edges curling up - calcium deficiency?
This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up. Is this just a straight calcium deficiency?

Aeroponics system that my fan leaves start browning on edge in 2nd week of bloom every time (about 7 grows in journey). Is this normal? Should i be concerned and adjust nutes at all? Or just selective trim any of the more "crispy" ones? Photo is 2nd-3rd week into bloom.
