Cal Mag for non RO water every feeding?

[Amphora420]

ive seen alot of people using cal mag all the time with n without having ro water ... i understand ro water needs it n cal mag issues are common so is it bad to use it every feeding with tap water as a precaution ??? the one i use says only once a week and thats about my watering length ... so is it ok all the time ?? n if not what are signs of over use ??? thanksssssss

If using LED lighting camg is a must. We use tap with a ppm of about 116 and add camg into every res change and have never had a problem save for one instance where the ph was running a bit low locking out the mg. Couldn't tell you why plants grown under led need extra camg but I'm sure there's someone on here just brimming with answers that will see this thread next. Happy growing!
