Looking good @Bunny . What kind of substrate are you using? Soil? Asking because of these Cal/Mg deficiencies, seems that I got some too, under HPS (but in coco) with added Silicium Flash. Seems to me that good soil should do the trick with the added Silicium Flash, but coco is lacking from the start, so it's not enough .
Nice Big Plants, Love it!
I'm growing in soil I would say the size of the plant in relation to its pot and how fast it uses up the nutes has something to do with it. My Telos plants.

Developed magnesium defs really quickly but were growing large really quickly in only about 15 L of soil. Maybe the intensity of the Telos is at play but I think larger plants may need top dressing with SF or watering with liquid cal mag. I'm trying 23L of Soil with 3 tabs and the full recommend dose of SF next run under GN Telos 0008.
That's interesting bunny!! This run i'd planned on 3 tabs in a 15l pot! - We'll see how the MG defs go under the telos! Spray at the ready!!
