Been battling with these plants for weeks now. Been holding off flowering until get it sorted but had to flip today. It does look like a mag def (interveinal chlorosis, hard, red stems) But i have been foilar feeding calimagic. I have cuts from them in perlite hempy, peat/perlite and organic. All showing same symptoms. Is this some kind of virus?

This is whats getting me confused. I have everything in correct PH ranges. The only thing i can think of is the tap water and the molecules are too large to be absorbed efficiently and end up accumulating on the outside of the roots

rooms temps 23c no idea about water content. I'm in asia and no way i would drink this water. Everyone uses bottled water here. But i have grown (very well) using same water. I always let it sit out for at least a day

Another good place to go when diagnosing problems-

https://www.icmag.com/ic/showthread.php?t=11688

It gives some info on other conditions that can cause mag. lockout. IMO, it def appears to be a mag. problem. If you're flipping it soon, or have already, you'll want to get this corrected- pronto. Going into flower with any deficiencies will greatly affect your end results. And it's a bitch playing catch-up during the flower period (if there really is such a thing)!
Never works out well for me.
Best of luck!
