It looks like a little nitrogen deficiency. Also noticed some brown spots so that could be cal mag. It could be a beginning symptom of ph issues or maybe lock out. It really depends on how you feed, what and how much you feed, ph medium ect. Without knowing those cant really say for sure.

I grow in a mixture of happy frog, ocean forest, peat moss, and perlite. I feed with Fox farm nutrient trio, liquid bloom, grow big, and tiger bloom mixed at half strength of the weekly soil schedule from fox farm. All nutrients are added to water and ph the mix to 6.0 to 6.5. All water I give is ph to somewhere between 6.0 and 6.5. Growing in 5 gallon grow bags that are elevated out of catch tray. Plants get good and light before watering or feeding.
