Part a Part B?

need advice any one use part a part b nutes if so how much per feed and i herd under dosing is better any truth to that ?????

what nutrients are you using

Sensi Grow A & B, sensi bloom A & B

-do not use the AN nutrient calculator off their website...its all fucked up.
-go off of the label of the bottle directly
- there are 2 sensi formulas, one is pH balanced and the other is not pH balanced
- the non-pH balanced formula requires 1.8mL per L of distilled or RO water for 600ppm for each part a and b
-sensi includes cal mag so do not add it

If your using it in soil, do not ph it too low or it will fuck up your medium and lower your ph to bad lockout levels.. I have been using sensi bloom for a couple of years and i agree with him telling you not to go by their calculator cause its wrong, I don't know what planet whoever thought that cal up but if you go by it your shit will get all fucked up.. Best advice when using AN's is get a ec or ppm meter
