Re: Can measure EC, but not components of
I don't know if there are ways to determine which element the plant is usingt the most of or the levels of each element but the way to combat a deficiency or aver abundance is to change out your solution and start over with fresh on a weekly basis. The longest you should be going between change outs is 2 weeks IMO. There are some who never change out and use a nutrient replacement schedual that is referred to as the Lucas Formula. I don't like the Lucas formulas as nutes are fairly cheap and the absolute best way is to give fresh every week or so.
