ok, let me clarify a couple things. it wasn't mushroom compost i had seen it was cotton burr compost with humus, it has no npk rating on the bag, but it seems really fluffy, i figured mix this stuff with the black kow composted manure and some perlite for a veg mix. does this sound like a plan? and i'm not planting seeds directly into it, i have a few seedlings that are about 2 -3 weeks old that i started with a mix of about 50 percent peat, 20 percent hyponex and 30 percent perlite, all left over from a previous op. they're doing ok so far i guess, but 3 out of 5 have these yellow/brown spots on the leaves, looks like cal. def. to me, exactly the same problem my last baby had nearly through the entire grow, but it seems so early to start having def. problems. anyway, that's a different subject i guess. thanks in advance
