mama mia fem and jack herer fem

three jack herer seedlings and 2 mama mia seedlings both feminized prepared a 1/4 gallon of RO water with a ppm of 8 and then mixed in my nutrients then mixed really well. then i measured the ppms and diluted the mix to 150ppms with 3/4 gallon of RO water then alowed it to sit for 20 mins for solution to mix well i then adjusted the ph to 6.2 and gave my seedlings a feeding til i seen some run off. i always dump out the run off so the roots do not sit in the water and drown. fed first feeding on may first and second feeding on may third using the same solution that is being aerated by air stone.
