What could be the cause? Auto Chem 6 week flower, in coco/ perlite, Dynagro nutes incl. calmag and silicon. PH for coco 5.8-6.2, 700ppm. 240qb light dimmed 60%, 20" from plant, 75-77 degrees 49RH. Help! Happened to my last plant too. This is only my 3rd plant so I'm a novice. Thanks.

Oh, and the lights were 20" so I just brought them up higher and I had halved the nutrients and just put them back in case this is deficiency.

I think your lights were too close.

Thanks. I made some changes today that hopefully will fix this. 20" to about 30", dimmed them a little and changed the light hours from 16/8 to 12/12. Here's hoping.

Way overfed and severe nutrient burn resulted.

Not sure. It happened after I went from 900 to 500 for a few days. Today I moved her back to close to 900 since that's the only thing I had changed.

I think too much food also, and possibly too much light also. Have you tested the ppm of the runoff after feeding? I bet its sky high.

What’s your watering schedule like with coco?
I keep PPM on most autos around 600 but water with this daily. Looks like maybe underwater/over feed

Ppm runoff was quite low bc I had flushed maybe a a handful of days before I took down the nutes. Then I went from 900 to 500 then this happened.

I fertigate daily about3/4 a gallon to get 15% runoff. Ppm was just under 900 for a while but she had no problems until now. Maybe I'll go twice a day now since she's having a hard time.
