Hi Taito, you have root problems from N excess combined with a bit of overwatering. Basically you can see this from the dark green leafs, the shiny aspect of the leafs and the downward pointing tips and with nutrient burn signs. Just reduce the amount of N and follow a "plain water plain water feed" schedule, so two times only water one time with feed (over ten days or so 3 waterings) . The RootJuice is also causing problems, try to replace it with something better for the problem roots such as humic acid, enzymes, or beneficial bacteria. For the overwatering issue, you can see this from the puffy space between the veins of leafs. Try to follow a more strict wet dry cycle. have you tried the "lifting pot method" to make sure you dont over water again? Hope this helps ! 🚀
