Hey there, bro! 👋 This is the result of a strong nitrogen excess! You need to reduce the grow additive, it has a lot of nitrogen! And you're already in the flowering stage, due to the nitrogen excess, there's a problem with phosphorus absorption! Use grow and bloom additives in a 1:3 ratio, and in the middle of flowering, don't add grow or micro (I don't know what you're using) at all... just keep the bloom additive in the nutrients! 👌😇👍 Good luck, bro!
