Hi all
I'm currently using GE's Three part line up, Micro, Grow and Bloom. I'm using their nute calculator but the EC I arrive at is very low. Always around 1. I'm at week 4 in flower and ive been using some House and garden Top booster to get the ec to around 1.4 to 1.5 H&G superboost is basically PK13/14 with added iron. To get the EC to around 1.5 im having to add 40 to 60 ml of Top booster to a 30 Ltr tank. I think i should really be using the GH 3 part more to up the EC, but in what amount? Should I stick to GH's chart but add more of each part to maintain their ratio, or just add more GH bloom only?
