Looks like Heat and overwatering + calcium deficiency possibly caused by Potassium excess.

Warum werden die Blätter auf einmal so schnell gelb und welk?Hey, my Hawaiian Runtz is at the end of week 4 of flowering. I water every 4-5 days with 2-2.5 liters of water and a pH value of 6.5, always pretty consistent with Terra aquatics pH drops, so pH errors should be ruled out. Temps during the day are around 28 and at night 26 degrees Celsius. What’s wrong?
