hey Lovni, So far so good, but as your soil indicates, you will eventually need fertilizers. Just a few tips: normally you want to fill your pots all the way to the top. Your humidity is way too low, so you have slower growth. Still, try to measure your pH, because it's going well now, but in my experience, long-term nutrition with what you're giving it can sometimes cause the pH to rise above 6.5 and that can cause problems. To wrap it up and tell you everything, normally even in soil, you want and need amendments for your medium. You're already using an additive, but normally you would want to change a bit of all that with 1. special flowering NPK 2. calmag (mandatory even in soil) 3. additives, especially humic acid, to replace what you're giving today. Honestly, 6 weeks on the package will be about 4 weeks in reality. For your humidity, I don't know why you're listening to that guy, but his advice is clearly terrible lol, take a spray and mist your plants up to six times a day if you can. Anyway, I'm trying to explain everything to you, but feel free to ask me questions if you need. I hope what I shared here helps you. 🚀
