CALMAG Def Question

If I note a calmag def 2-3 days after a nute change, can I add a small calmag solution with Ph'd water? Or do I have to change entire feed rez? Ty in advance.

Add. Keep total EC in mind. Watch for any nitrogen toxicity.

Thanks. Yeah I was worried about nute burn and EC was @ 1.2 prior to adding some another 5 ml of calmag. Im going with less is more in regards to nutes, only running lucas formula as well.
