There are 3 plants in this tote (2 bubblelicious and 1 blue cheese. Only one bubblelicious had these symptoms for a week or 2 but I notice a little starting on the others. They are auto's in their 9th week. IMG_20191212_054438649.jpg

Ph has been starting to drop lately also. Since beginning this grow it has always stayed stable 5.8 to 6.0
Edit as I probably should have mentioned I use calmag. Nute ratio since beginning is 1 part micro, 2 parts bloom, 1 part calmag
 
Yes, it looks like Ca def. Is it 9 weeks from seed or flowering? The pH typically drops during late flower. I wouldn’t worry if you only have a week or so left. If you have 3-4 weeks left, I would bump up the CalMag a bit. At 400ppm, you have some room to increase your nutes.

They are 9 weeks old and well into flowering but still several weeks to go I think. I was hesitant to bump up the nutes as the bubblelicious starts to leaf curl any much higher. I did do a rez change yesterday but after reading your post I bumped up the calmag a bit. The other bubblelicious and the blue cheese in this reservoir looks ok and the plants in the other reservoir look a lot better but there are a very few with some spotting.
Thanks for the reply
