How old do the seedlings have to be before I start adding nutes to my water? Also do the nutrients come with instructions. I mean as far as how much to add per gallon of water? |
you need the micro. you can actually get by without the grow if you would like. look up the lucas formula. it just uses micro and bloom, since the micro contains plenty of nitrogen.
directions are on the back, but you always want to go off what your plants need, not what the bottle says.
seedlings usually need fed 2-3 weeks after they sprout up. growing in rockwool, maybe a few days sooner, since it contains absoulutly no nutrient value.
always start off at low strengths, never the full dosage.
1/4 tsp of each would be a good first feeding.
