Co2 causing deficiency?

I just transferee these plants over from veg and the plants started doing this. They are under a hlg 600h led fixture using jacks 321 nutrients co2 ppm set at 1200. It only started doing this when i add co2. What would be a good remedy to this bumping up the feed maybe?

That stripey burn pattern is common with a pH problem, The medium pH could be off, it has to be pretty far off to do that.

It just started doing this right after I put them In the flowering room with co2.

That's weird. My last round did the same thing after I added 1200ppm 1 week into flower. Didn't hang around long, and it out grew it around week 4. PH was a bit high tho at 7.2ish

maybe dial down the co2 then?

co2 doesnt cause deficiencies. its something else. is your ec and ph and temps on point?

Co2 techno babble.

When running co2 I find everything has to be dialed in well. If your ph, ppms, environment- temps are off it can cause problems quickly. Its like a symphony in perfect harmony then if one note is off it can throw the whole thing off. So many things but as Renfro said ph of soil could be off. Are you supplementing calmag? They almost look like they could use a lil N. I run veg nutes 1st 10 days to 14 days in flower.
