Looks a lot like symptoms of overwatering. What medium are you in? How often do you water?
50% Cocoa 30% Pythagoras 20% Perlite, Temperature 25 Humidity 45, 7 liter pot I water 1 liter every 3 or 4 days, aren't these signs of phosphorus or potassium deficiency? Because it is only seen in old leaves
The yellow pot plant is completely lifeless. I think there is a lack of nutrients because it is growing very well. Now in this photo, it is 40 days and it is 2 or 3 days.
What nutrients are you feeding the plant and how often? Also, what is the pH and PPM of the runoff?
@Mr. Grow It ph is 6.1 and ppm is 400 day 40 my pot is 7 litre
