Chow_13answered grow question 3 years ago Is this the top most part of the plant. twisted new growth can be a sign of light burn. Also serrated edges curling up is another sign. I can see in the background the leaf has some minor interveinal chlorosis which is usually a nutrient issue but can also be cause by light. Are you seeing any other signs of anything( brown spots, twisted or deformed growth, color differences) anywhere else on the plant? Your current feed ratios look to be in the right range. Might want to slightly increase the boost a bit since that's the only one I see you going on the bottom end of doses in the feed chart.
I would say raise the light if that bud site is the higher and more centered bud site or if that is the only bud doing it and its the heighest then you could bend it over to even out the canopy and keep the light as is.
Happy Growing
