Has anyone used the 3part formula for GH..I'm on my 1st grow and need help on how much nutes of each to add to each gallon of water to make the tds meter read 1200 ppms..I really dnt know much about the nutrient equation to dtermine how much to add! I'm going with the recommended on the bottles..but wen I do my tds reads 2000 ppms..is this ryt for the gh recommendations?I'm on bloom cycle.. Or is my tds meter off?

calibrate your meter before taking any readings...That should be 1st.

Then mix your nutes/adjust ph/take readings.

You can go to the GH website and they have a calc you can use that is handy. I find less is more with nutes. If your tds meter is calibrated, then it's accurate.

Yeah i have a couple of those calibration liquids..do i calibrare it EVERYTIME i take a reading? Which is everyday for me..or should i read it less frequent? I also adjust a lil ph due to water evap. And also add water everyday!
