During veg I gave it urine for nitrogen one month after sprouting. Than I gave it a top feeding of compost, and epsom salt. During bloom I gave it a top feeding of epsom salt and a liquid feeding of raw coconut water 2 weeks into bloom and again 4 1/2 weeks into bloom and now I am only giving it water ph at 6.2. Also if u want to keep it totally organic use apple cider vinegar as ph down and baking soda as ph up.
