P.S. I’ve needed all the warnings about over-feeding and over-watering. I just checked the soil. I’m very happy with the drainage of the HF 66%/Perlite 33% mix. The soil is dry on top down to the first 2 or 2.5 inches, and then darker (moist) below, but barely (after being watered lightly yesterday, and only mistings on the top other times). It seems like tomorrow might be the perfect time to water the soil girls (lightly with VERY diluted nutes and some probiotics).
Since the coco plant seems overly moist in comparison, the growth has slowed vs the other five, and the color is brighter, my assessment is possibly poorer air flow and lack of nutes vs my soil ladies.
My exhaust fan is presently running about every 5 min for 30 seconds. Temps are maintained at about 80, with humidity ranging between 50’s-70’s. That said, what I may do (both to ensure the 5gal soil pots are adequately dried in preparation for their watering in the morning AND to attempt to dry out my coco medium) is turn the exhaust on without interruption though the night tonight. That may kill two birds with one stone for me.
I’m already learning a lot, and in retrospect, I would have kept the mediums consistent and just done the HF/Perlite. My little coco plant is really already lagging behind. However, I suppose that was sort of my intention for my first grow: to learn lessons, refine my techniques, and see what works the best.
