What do you think the issue is? I’m using 900w V...

Your plant looks just fine right now ! You can choose that answer 😘

You got weeds growing in your weed...like me lol. Pluck those babies like the others mentioned. So potassium is needed for plants to produce chlorophyll, which in turn allows the plant to generate energy from absorbing sunshine. It also helps with root growth like clones and every other stage of plant and aides in fighting away diseases. Between a nutrient schedule with good potassium and also adding in some mycorrhizal to strengthen your soil health the plant should do spectacular. They do look great already. 👍💚

As you're probably using old soil, i recommand using enzymes... Like cannazym or something else.. It will change dead roots into nutrients for your plant...

Your plant looks healthy but those clover in the pot need to be taken out. Those have no place being there and can cause a lot of problems. As far as soil goes usually you can get away without having to add any nutrients until the later weeks of veg early weeks of flower. Try using a soil like fox farm ocean forest as these have plenty of the nutrients you need for the early stages of growth. Your top nutrients you need during the entire growth of the plant are your basic NPK’s. (N) Nitrogen is more important during veg and (P) phosphorus (K) potassium are more important during flower. Make sure you are using quality soil. Good luck!

Leaf color looks good and plant looks healthy. That been said I notice that you have smaller weed growing in some of those pots, like clover or something like that, how did that get there? I think you might be using low quality soil, like something you got from your back yard, or reusing old soil. 30 liter of soil would allow you to grow monster plants without adding any nute, I know that my 11 liter pots gives me 7 to 8 weeks before needing some bloom nutes. Take out those smaller weed that are using your precious soil nutrients.
