The dosage sounds correct. 7ml of A and 7ml of B should give you somewhere around 1-1.2 ec. Your ph needs to be higher 5.8-6 and you want to feed every day. You are letting them dry out too much waiting 3 or 4 days. That's why they are dropping like thatpH 5.6 I have only been watering ever 3 to 4 days with 7 ml of Coco a and b nutrients diluted into 3 and a half liters of water is this wher I am going rong I mix it into water and let sit for a day or 2 stiring it ever now and then then pH to about 5. 6 then feed plant a liter at time wait 5 ten min and use about 3 liters or untill I get a little run off thanks
