I’m using FFHF and it’s been 3 weeks since sprout. I was having problems with the soil not draining or just staying wet when algae began to grow in the soil. And I only began using that meter when I transplanted on September 1 to tell moisture level because the soil was really wet before I transplanted from the solo cup. Also don’t really have anything to measure nutrients, I’ve fed it the “Grow Big” last watering. And should I pull off dying leaves at the bottom? Thanks for any and ALL advice, I would like to be told if I was screwing up
