I have 3 plants that are 9 days old. One of the plants has spots on the leafs. I am not worried as they are in seedling soil and had their 1st feeding today. They will switch to organic soil in a bit of time as well. The feed I gave them today was 1ml of floranova grow in 1l of water. The PH of the runoff was 5.8. I will try to post a link to my other post with pictures of my entire set up. Thanks in advance guys and gals!
