What is your growing medium? If you’re growing in soil I highly doubt it’s a cal/mag issue as there is plenty of cal/mag for a grow in most quality soils, more likely you’re Experiencing pH fluctuations in your medium.

Vague, though I would probably use calmag...but then, I'd probably also add a bit of sulphur and phosphorus if I have some.

1.0 ml of calmag per 1lt will do it wonders for next week or 2. Then start lowering it 👍🏻🌱❤️🍁

Leaves damage: PH levels from nutes?
Chemical question: growing 3 autos since 3 weeks, last 2 days had symptoms of deficiency after adding 1ml/L of Calmag, BioHeaven and B'cuzz root stimulator, soil is Kilomix which has PH 5.7, tap water has PH 8.1, is it possible that nutes made PH that acid/basic to hurt plant?

Nute burn or pH Flux
Ive noticed the tips are the faintest of yellow. Maybe ive mistaken Nute Burn for pH Fluctuations? Diagnosing: pHing both tank and run off showed different ranges. My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.
