How has the transition to COB lights effected your grow style?

Just to clarify, is the purple stems a sign of cal-mag deficiency, a different deficiency... or nute lockout?

To me i would flush plenty of water then feed with synthetic nutes that are correctly ph to 6.5 or so.
Coco has ability to take away your cal mag as well. I'm not a soil grower at least not now lol. I used to run happy frog and if I got lockout I just waited till it was really ready to water and flushed the crap out of them being sure to feed with the last gallon or so lol.

Also use 10 ml cal mag+ hard to overdo cal mag

Thanks for that @Stephenj37826 . I'm an outdoor gardener stumbling through the transition to indoor. I've done a few series of indoor grows but I'm still leaning on the old school paradigm of potted plants... sorry, long way of saying I have yet to set anything up that would allow me to "flush". The whole concept just seems wrong somehow, but so many indoor growers talk about it like it is invaluable or irreplaceable. My hope is to add nutes slowly enough that I never overload them, but now that's coming into question as the COBs (apparently) push the plants to use more nutes, or use them more quickly than I've been compensating for.

Wanting to stay organic is commendable for sure. I'm more on the lines of a mixture of the two worlds as much as possible. I run full synthetic line with added beneficials. I love super bat budswel liquid. To me it's really hard to get the plant all it wants in soil. If it was me and I wanted to stay organic is look into liquid organics. Mission fertilizer brand might be good stuff. I've read good reviews.

LOL, yeah, I can see why what I said came across as me saying I'm going full organic. Not the case. What I was saying is that I use a pot with a tray under it... no "drain tray" that drains into a bucket or bin or drain, no way to put them in the bath tub and flood them. I'm just not set up for flooding. And the part about it not feeling right, is that I spend enough money on nutes and good soil that flooding away all that goodness because I overdid it, just doesn't seem right to me. For medium I'm playing with a coco/perlite bottom layer, with a soil mix on top, but I also use some GH dry nutes added to the water when needed. I guess with the COBs I should expect they'll be needed more and more.
