My bottom 2 leaves have a few very small yellow spots. I've heatd that I should start by checking PH and then go from there. Anyone have any suggestions if it is PH?
Don't worry mate it's really easy, once you are sure you have a ph issue you just need to get son PHdown or PHup and follow the instructions to get right ph for your next irrigation. Have a nice grow 👍 good lcuk😁
