Watered in some more Epsom Salt and added some soil to the top of each cup today. They look a lot better in this pic than they did a couple hours ago. Still signs of magnesium deficiency and also a few brown spots. Not going to transplant until next weekend, as the tent isn't ready for them.
The soil is 2 recycled, reamended batches mixed together with some Coast of Maine Lobster Compost. 1 batch was reamended with BuildASoil craft blend 3-5-2 and mineral pack, CoM compost, charged biochar, and some kelp meal. The other 1 I don't really remember, I think it was a new soil mix with some recycled soil with Dr. Earth fertilizer, Kelp Meal, BuilaSoil worm castings and mineral pack.
Both soils cooked for a long time, but not in ideal temps until the past month.
A few other cultivars look extremely healthy with this soil, however 1 is showing worse signs of magnesium deficiency. When I mixed the 2 soils together and Compost, it's likely I didn't mix it well enough.
