You don't need something to neutralize alkaline soils... hm. sounds like that was designed for outdoor use as an amendment or top-dressing. The one with all the meals in it sounds crazy-hot. You may well end up flushing... PERLITE...
I'd add more perlite to both of those. I like 'forest humus' but the peat content of both is kinda like corn in dog food- a filler that can cause nutrition problems.
