Phosphorous and potassium deficiency. A P/K booster will fix this. The damaged leaves will not recover, but it will prevent this from getting any worse. Both these nutrients are needed in larger quantities during flowering.

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?

Is my plant showing signs of Nitrogen deficiency?
Autoflower, day 40. Most leaves are in a yellowish-green tone or even completely yellow. I was mistakenly watering it with tap water, but when I noticed the yellowing, 1 week ago, I started watering with mineral water at pH 6.49.
