I'm a new grower using Promix UP, maybe someone can help here:
I'm using Maxigrow/Maxibloom with soft tap water (<100 ppm) so I've been treating it like RO water. I supplement with about 200 ppm of cal mag every watering but it seems every grow I get the red streaking on the stems and branches. I know that my base nutrients contain some calcium and magnesium also so I'm not sure where I'm falling short.... Or maybe I'm overdoing it?
I'm using an LED light providing around 700 par at the canopy with good temps and air flow/exchange
On day 11 since flip to 12/12 so I decided to get at least one foliar spraying of magnesium before the bud sites start to form.
Current Water/Feed Routine and Stats:
Input ph 5.8, Input ppm around 800
Output ph: 6.1, Output ppm around 1200
Feed 200 ppm Cal Mag, 600ppm MaxiGrow/Maxibloom
Watered until around 10-20 percent runoff
Here's a few pics of the plants and some crappy looking clones I took, HA!

Thanks for any help, advice, suggestions, and/or good natured ribbing
