As far as calmag goes when I went 1tsp per gallon my ppm went from 150-600. I read everywhere this is to high but I still see cal deficiencies. I even bought another ppm meter as well to double check but it doesn't seem correct.

This is the setup now.
Cal/mag issues when PH is good usually indicates root problems. I'm not one to use bottled anything, but I've been using Hydroguard for a while now and I even add it to my plain RO water. I think this is a product superior to any other of its kind, I highly recommend it. My coco grows have gotten much better since I've used it. It kills detrimental bacteria in soil and hydro.
I don't think it's a root issue. I usually inspect the pots once the plants are chopped. I think It's either I'm adding way to much or not enough. In veg they are amazing and once flower hits it seems to turn a bit. It looks like a combination of calcium, phosphorus and potassium depending on which plant. It's starting on lower leaves and working upward so I would guess it's missing something. The smallest plants look the best, the most advanced plants in flower look the worst. I have been staying steady at 50% the recommended strength but it may just need more. But then again I am seeing some tip burn too so that holds me back.
Sorry, a correction:
Hydroguard does not "kill detrimental bacteria in soil and hydro." It is bacteria that digests organic crude (with plant nutrients as a by-product), and is not going to kill anything. According to Botonicare, "Hydroguard® contains unique beneficial bacteria, Bacillus Amyloliquefaciens, selected specifically for its superior ability to enhance the symbiotic relationship between the roots and their surrounding medium."
This product, the Bacillus bacterial strain in Hydroguard, has nothing to do with photosynthesis. Hydroguard is bacteria that digests most non-living organic crud in the medium/soil, indirectly providing more nutes for plants and other microbes.
You may be referring to some other bacteria-containing additive products claiming to increase photosynthesis, such as Photosynthesis Plus/Microbe Life. But if you read its description, this (and presumably others) has nothing to do with photosynthesis, is more just boosting nutrient intake and metabolism, and indirectly having any effects on "photosynthesis" .
