I have seen signs of brown spots for a few weeks now. Any ideas what this could be?
Notes:
- they've been in flower 2 weeks
- nutes were floranova and cal/mag to 1300 ppm at .5 conversion
- ro water
- 1000w hps
- dwc
I just switched to Lucas formula today, 8/16 micro/bloom with no cal mag...see if that helps. I have an intake into the Mother room then a hole up top that feeds into the grow room. The exhaust pulls air out of the grow room. I was wondering if the grow room could be lacking fresh air. The temp goes up to 28 Celsius.
