I know there are a ton of threads on Jacks & using various ratios but I wanted to start one that related to growing with Jacks & what have has now been classed as high powered LED's, i.e. cobs (CXB's,Vero's etc), Samsung strips, quantum’s etc.
As many if you who have made the jump to LED are aware there seems to be a greater demand for Calcium or Magnesium or both when growing under LED.
I'm just curious to see if any of you have roughly nailed the Jacks, Calcinit & Epsom ratio's for growing under LED? Or has anyone found that the 321 approach has worked well under LED?
