Hi there , without a diary it’s hard to say exactly , but that looks like micronutrient deficiency and a bit of overwatering. You can see this from the “too green” aspect of the leafs , the downward pointing tips and the yellowing affecting the newest growth first. Reduce any N you are feeding , add cal mag, and most important be very careful when you water . Make sure you follow a very strict wet/dry cycle. The good news is you caught the problem early so the plant should recover quickly . Hope this helps ! 🚀
