It must be mag which is good because i just watered with calmag+ yesterday so hopefully itll get better
I doubt it's light stress because I've never had that issue with autocobs. Had them almost touching the plants without issue in flower. Right now the light is 15" away

Hopefully it rebounds. If it doesn't, it may also be a nitrogen issue. It does look like a Mag deficiency to me though. Make sure your PH is in check, or you could have a lockout situation.

And thanks for rep!

hello are you using cal/mag every feed

You need less light in initial flower than veg.

I ramp up to 45 DLI in veg if it can take it, I drop to 25 at first sign of pistals, and increase it 2-3 every week, up til 40. The lase 2 weeks before harvest I turn it down a little.

The plants look hungry in general.

If this is straight coco/perlite, i.e., soilless and no compost or other organic matter, you'll need to be feeding nutes with calmag every watering and avoid letting the medium dry out.

The latest feedchart is here: https://generalhydroponics.com/wp-content/uploads/MaxiSeries-Performance-Feed-Charts.pdf

PPM's are given on the feedchart. For autos, aim for 500-600ppm, so this will be closer to full strength of "light feed" from the link above. Note, the cal-mag doses on that feedchart are not great for coco, and should be bumped up a little. Closer to 3.5mL/L is probably a good starting point for vegging cannabis in coco. Careful with playing with doses on feedcharts in general, but I have done the math atleast for GH Flora Series, and nutes stay in balance with that line up when calmag is bumped up a smidge for coco grows. Just make sure your ppm stays within bounds if you bump up calmag.

I don't have a ppm meter
