Because the soil pH is in an alkaline zone your plants show signs of lack of micro and macros nutrients calcium magnesium manganese sulfur, a good option would be a fresh soil mix of umus organic compounds, manures, guanos, algae extracts supplying soil deficiencies and feeding bacteria, I recommend a larger 15 to 20 liter pot and using serious mycorrhizae is a great choice, root space and a mix of fresh soil is the best way, you can also take light doses after transplanting with 150 ppm NPK At 200 feeding via stomata the food arrives faster supplying deficit helping in chlorophyll. I wish you a great grow up good luck friend
