Here I'm trying out DWC to save space. I've been searching around the web to get some input when to put some notes in my seedling. Because I never put nutes early in the seedling on my first plant. Everywhere and almost everyone suggest I put them in when the seedling shows second sets of leaves; so that's what I did. I put ¼ strength. My ppm's were up to 440. I was worried to leave it over night. The next day my seedling looked burned. So I switched back to regular pH. I have some pictures showing my progress. My temp and humidity are at a good constant level. I just don't want to introduce nutes too early or too late. In my pictures the older plant is a underdawg og, and the younger one is a killer triangle og.
