I was just looking at an ir/deep red light. Thinking about the same with the cobs and cal-mag deficiencies.Its interesting that under LED the plants use more Cal or Mag or both. Something to do with lack of IR or something.
I noticed that going from the 130w cfl to the 100w of strips I had to up my dosage. I just use the bottled cal/mag. Lasts ages and is easy to dose.
