Hot Soil Burns Sprouts

Rich amended soil designed for flowering plants will scorch a seedling, and the burnt leaf tips on a week old sprout get blamed on the seeds more often than on the mix. Young roots want a light, low nutrient medium for the first two weeks before moving into anything heavy. The seedling mix recipe on https://potentthcseeds.com is peat, perlite and a little worm castings, and my THC seeds have come up cleaner in it than in any bagged super soil. Save the strong stuff for the final pot.
