When can I give my seedlings nutrients? Right now they are just about an inch. My medium is a soilless medium mix of quality Canadian sphagnum peat moss, Softwood bark fines, horticultural grade vermiculite, perlite, very little earthworm castings, bone meal blood meal, I set up my air exchange. This are my little ones.
Until at least the third or fourth node at least , right now just give them good light and let your soil dry out ah little before watering , you don’t want to drown your roots this early by over watering .
Include a root stimulator now at this stage also cab us thru-out grow. Start nutrient use in week 3 at very reduced rates (1/8 amounts and then working up to only 1ml per liter)
