Terp1answered grow question 9mo ago Nutrient supply seems good but not toxic. I'm guessing it's environmental conditions. Maybe a bit too much water over a longer period, lower the light by 5% or hang it higher, is the VPD under control? Right now, 1.2 - 1.3 kPa would be optimal. About 25-26°C at 55-58% RH. Don't worry, it's nothing serious. As long as it only focuses on the tips and doesn't spread, everything is on track. Overall, it looks very good. 👌👽
