Robertsanswered grow question 2 years ago Start adding new weeks on your diary so it provides a better picture to read for diagnosis please. What it looks like to me is a water issue with that plant. Plus light intensity is too strong. Turn down or back off plants some. Leaves will stand up in praying fashion when you find the sweet spot for that stage of growth. You are a little heavy on feed as well. The darker green is starting to show. If giving nutes maintain a run off of at least 20 percent. If in soil they need a wet, and dry cycle. More information would help of course. Ph readings, ppm or ec readings, what substrate, what's mix consistency parts and how much. I think you need more perlite in that one to solve watering issue. Improve plants resistant to it. Good luck
