Heres a couple that r wk n half in veg..in i kinda go by old skool methods so there is a pre-veg...whenever u root(get multiple roots hanging,roughly 5 strands hanging) i flip them over to 450-600ppm.that i call pre-veg..once hitting my target 1100ppm,(5 days after hitting the 450-600 ppm)thats wen i start veg.so if yur truly counting days n not stages,20days
