Reading the plants...Truly amazing--great show!kinKy said:im not using any type of meters (only temperature heheh) ... ph and ec is being regulated by what plant shows. i only give filtered water with hesi, theres nothing that can drift the pH very much, the sativa ones (durban poison) shows a little deficiency due low ph, i added some "calcareo dolomitco" (i think is dolomite in english?) and its ok untill now.
very thanks for the passin by.
