Leaf Problem: Can't Troubleshoot

[Space cowboy]

So I'm just going to get into it.

I'm about 6 weeks into flowering a lambs breath auto from crop king and I'm getting some leaf symptoms I can't figure out. I'm running a 5 gal dwc bucket with 2 air stones. I can't remember the pump specs but its commercial grade, so all good there.

Light: 800 watt led 20/4 schedule
Water: RO
Nutes: Mad Farmer bloom 450 ppm avg
12(3/gal) ml bloom city Calmag
Hydrogaurd

I check ph in the morning and afternoon daily, and don't let it stay outside of 5.5 to 6.4

This is my first grow so I'm still learning here. Any help is appreciated.

Cheers

I had the same problem on my afghani #1 in DWC but adding a little extra cal-mag cleared it up. You seem to be a little gentle with the cal mag.

Thanks for the tip. Just upped it. Hopefully it didn't stunt my girl. I guess we'll see
