Cor das folhas da gema de cima

Overall looks healthy and would not be worried, like others mentioned new growth is often a bit brighter. The leaves look slightly dark and good be an early sign of nitrogen overfeed, but hard to tell and could be camera and light; if they start clawing or turning down, lighten up on nitrogen feed. Another telltale sign is older leaves will start to get tip burn. Another place to look. - Moisture on leaves might be an indicator or just a coincidence / timing of pictures. Just in case, make sure your vapor pressure is correct. Check out any VPD table for cannabis (google search images) and verify your in acceptable range for temps vs humidity. Typically i aim for 75 degrees/70% humidity.

Hi buddy don't worry first :-) How high is your Ph value, how high is your Ec value and how is it watering behavior and interval? :-)

Hello.. Hope you are well.. Tbh i think its just from her fast growth.. New leaves will b lighter than ones in full growth.. I also notice her leaves are wet.. Are u spraying her while lights are on.. Dont do this if u are.. It will burn her leaves.. If u want to spray her do it wen lights are off and let her dry b4 ur lights come bk on..
