hey there Rova , downward pointing tips is a sign of root zone issues, in your case it's a very light water mold issue, probably due to slight overwatering you can sort of tell from the puffy space between the veins of the leafs. So you're already using a chelation agent with the floragro meaning it will break down the problem roots and fix it once you dial in the watering. Just let it go a few more hours than usual like 10/12 hours . Keep a strict wet/dry cycle and the plant will recover in 10 days or less. Hope this helps ! 🚀
