Calmag deficiency

NorthernStar20started grow question 5y ago

The leaves on my plants seem to have some markings appearing, I havent yet given any calmag. The plants are in their 4th week from planting seed. Also seem to have some nute burn going on. I do have some biobizz calmag, should I use this and if so at one strength?

Looks like a slight nute burn and, yes, she needs calmag. Check runoff and make sure its between 300‐500 at this point. Feed calmag as directed on the label (one of the few nutrients this is okay to do). If your runoff is much higher than 700, do a flush.

Your best to check your runoff ph and ec before over reacting. If your high on nutes adding cal/mg will only make things worse. Cheers friend

Light burn?Is this light burn, or something else? Plants are getting very close to light. Leaves not directly under seem okay, so leads me to believe it's light burn.
