Plants are light green

Hi, I can't see any nutes up, what are u giving them for feeds? By right in week 3 you should be aiming for an N-P-K ratio of 3-1-2 3 parts N 1 part P and so on. In a more simple term. Any decent grow nute and aim for a range of 4-700ppm and get some cal mag as you will need it, and if you want a true color of your plants you need to look at them in natural light or turn off your led light and take a flash pic as the led light/lights make your plant look a lighter shade of green, they look fine but are showing early signs of either wanting nutes, as idk if you are applying nutes or down to PH swings, or just off PH. Dunno what that means the pigment will pick up, your pigment is controlled mainly my PH. So, if anything it'll get worse if you are using too high or low a PH. 5.8-6.3 you should be aiming for. DM me if you want more info on feeds and when you should start to push more P-K and less N. Good luck, happy growing.
