My personal feeling is that’s the very early beginning sign of some sort of imbalance developing.
Are you able to check if the bottom of your buckets has gotten too saturated with water and gone anaerobic? If not that, then I might add cal + mag.
If you’re still using the slower release organics and haven’t done so yet I would definitely top dress with a bloom fert now. It looks to me from the deep green in the lower leaves and very slight possible clawing + deeper green tips on the upper leaves that you have way plenty of N, but probably other thing(s) are starting to be not enough or just unavailable.
I’m not a wizard at fixing nutrient issues (maybe some day
maybe not but you seem to have a good eye for leaf color.
looks like mag to me also. seems to be mostly the tops closest to light. maybe pushing dli a bit hard also
I hope im on the right track this time. Usually the next week or 2 is when it starts to go south. Only on my 3rd or 4th organic soil grow. I didnt anticipate the learning curve.
What @Gpaw said. I do try to keep autos growing as fast as possible in the first month. Also its partly genetic because a couple i have going aren’t as girthy at the base.
