Calcium deficiency. Add cal/mag to your line up or increase the dosage if already using a cal/mag supplement. Remember too, what is showing now in the leaves, is a direct reflection of what was happening in the root zone 2-3 weeks ago, meaning this issue has been manifesting for some time already. Also, improvements will take 10 days or so to start showing up, it won't happen overnight! But the sooner you start, the sooner you prevent the issue from becoming worse. Damaged leaves will stay damaged unfortunately, but there is no reason to remove them just because they "look ugly".

Brown spots I'm having what I think is a cal deficiency. Ive been using calmag for a week or so now. Just curious if this will ruin my end results? It looks pretty bad. Buds still look nice though. Any thoughts?

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.

Is this a disease caused by a lack of calcium and magnesium?I pruned these problematic leaves during the flowering period, wondering whether this would lead to a decrease in yield. Calcium and magnesium were added every time I applied fertilizer. What caused the disease? Overnutrition burn?

Was ist das?Meine Gorilla Skittlez (siehe Tagebuch) wird relativ hell und bekommt komische Flecken. Ich gieße abwechselnd mit Hesi Bloom (2,5ml/L) , 1ml/L Calmag und nur Calmag 1ml/L Dachte die Flecken kommen von zu wenig Calcium Magnesium. Jetzt steigt aber mein PH Wert von 6,8 auf 7,4.
