Hello everyone, So, I decided to follow advice and start fresh, planted a new seed. Again, the lower fan leaves are starting to have sighs of drying out leaves. All signs show nitrogen deficiency, I just don’t know what I’m doing wrong. Like my previous grows, it’s an reoccurring problem. I know the ppm is low but the all mix should cover the rest. Their growing chart, recommends 1ml through the whole grow.
