Hi
@trilldex420! Your plants are asking for Nitrogen, the yellowing on the lower leaves is a sign of a N deficiency. Have you been using any fertilizer? If not, then it's probably time to give them a good meal. If yes, that would mean there is probably something wrong with your soil because plants cannot handle nutrients intakes anymore. In this second scenario, a good flush before a transplantation to a smartpot with a fresh medium would help solving the issue. Hope this will help, keep us up-to-date and happy growing! 👊
