I'm growing a mandarin autoflower in my trash can/spacebucket. She is 13 days old and in happy frog soil and perlite. I water about once a week with no nutrients yet. I have fox farm trio to use when it comes time. My questions are how does she look and how old should she be when I start feeding her and when should I start LST? I know to feed her 1/4 of the recommendation for photo periods. I appreciate everyone's help in advance.
