Hey bro! 👋😇
Your plant is not doing too well!
My guesses:
1. You're probably overwatering it! In a 1L pot, it only needs about 100 to 150ml of water at a time. Water the plant when the top 2-3 centimeters of soil are dry!
2. There might be a problem with the pH of your water and, accordingly, the soil! The acidity in the soil during the growing and adult vegetative stages should be maintained at a value of 6.2-6.3 pH.
3. I don't know the ppm(ec) of your water, maybe you're using hard water and, as I understand, you've started giving nutrients! Perhaps you're giving too many nutrients, considering your water is filled with minerals.
I recommend keeping track of the pH and ppm of your solution in your diary! If you don't have control devices yet, I suggest you get them soon. The price for two devices (from a Chinese manufacturer), for entry-level, will be around $20 for two electronic devices... for example, a ppm meter with a coefficient of 0.5... and a pH meter with temperature compensation. $20 and you'll already know a lot about what you're doing with the plant! Also, advice and recommendations will be much more accurate if you encounter serious problems and bring them to the questions section! 😇👌
Good luck, bro! 😇✊
