Magnesium nutrient lock out, triggered by too much potassium ?
@Burmese Thank you so much for your help. 🙏😊 I think it was a magnesium nutrient lock out, triggered by too much potassium. I sprayed some water with Epsom salt on the leaves and it looks like it is getting better. 👍😉

Help calcium deficiency
I think I have a bad case of calcium deficiency? This started shortly after switched to 12/12. I added 1/4 tsp to a liter of water 2 days ago. I’m not seeing improvement. Am I right ? Will the leaves turn back green (how long)? Is it something else? Will it die?

Dry or Feed?
What should I do to fix my plant? She has hanging leaves and yellowing for weeks. The summer has been pretty wet here, and the soil has been satiated a couple of times. It's getting dry now. Should I wait for the soil to completely dry or try feeding nutrients?

Желтеют листья.
Всем привет! Выращиваю первый раз, сорт Auto Opium, растению месяц, нижние листья начали желтеть и вянуть, это связанно с переходом на цветение? И за какое время растение будет готово к харвесту? Заранее всем спасибо за ответы😄💚

Yellow bright new growth
New leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?
