Deficiencies while in late flowering during flushing period

Hi there Kripoulas, well, you're right about calcium deficiency. Giving calmag isnt such a bad thing, probably it will be useful, but you can really go either way. My advice would be to add it back again , then do an "additive flush" which is a flush but with additives like enzymes, humic acid , or h2O2 , if you add additives you can cut the time of the flush a bit down, so you can have the plant recover, and do a flush before harvest. Hope this helps ! 🚀
