I gotta disagree. Yes a seedling needs nutes to grow & live. But we're talking TINY amounts. So, no it doesnt need extra nutes, bare days from germination. Even crappy potting soil will keep it fed & happy for at least a week, maybe 2. Shoot, Fox Farms Ocean Forest can grow light feeding autos out just adding water! Maybe a little mollasses to help the yum-yums in the soil, but thats about it. Some folks like to give nutes to help speed seedlings along - but Iv never NEEDED it. A little mykos sprinkled in the starter pot & again at transplant, using FF- ocean forest soil, just adding water. Great organic weed if you know what youre doing & dont veg too long. Just keep up on your pruning & lollypop it. These techniques help shunt a higher % of nutes to the buds, decreasing the likely hood of deficiencies. Hope u can find a nugget in there thats of some help. Happy growing!
