Im not a Coco/soil guy so I can not say for sure! If things are already working for you I would not change anything with what you are doing!
I used to grow plants with a claw, tips point/curling down. The tips would be burned a bit...........
5.7ph for the starting poing of the nutes if you drain to waste in Coco should be good, but again, I grow in hydroton. I dont even seem to remember where I learned to keep the ph at 5.7. Maybe a Coco guy can say for sure if 5.7 is ok for that medium, but to me hydro grows in rocks are meant to be indoors, a strict 5.7 PH and sterile!!!!! As in add bleach at 1/2 gram per gallon of water to your mix in ebb and flow! Much cheaper than DMZ. I do spray my plants with DMZ though.....
Epson salt is used to add Mg and S to your formula only if needed. It is MgSo4, or Magnesium Sulfate. It breaks down to Mg and S. You never if ever have S problems, so dont worry about that. Too much S is also rare if even possible as it would be locked up by Calcium before plant damage could occur (Jim McCaskil).
Jacks mix has around 63 ppm per gallon of Mg at 100% strength. I run it at about 75% so thats around 47 ppm of Mg. I add 30 grams of Epsom salt to a small quantity of water and throw it in the 40 gallon barrel reso of water for the plants you are refering to in the bucket system. I believe im sitting around 67 ppm of Mg (aprox). If I see an issue I know to add a touch more ppm of Mg.........
I believe roughly, and someone correct me If I am wrong, that 1 gram of Epsom = about .5 ppm of Mg. I usually add at least 1/2 gram to 1 gram per gallon of water on top of the Jacks just for shits and giggles. The added S adds to the plants flavor and aroma, however that is another topic of discussion.
Mg deficiency can be seen in some strains. StarDawg needs more Mg than other hybrids! Most people, when they have a Mg issue have a lock-out of some sorts as most nutes supply enough Mg in their formulas, however, they assume its a shortage of the element. Throwing added PPM of a particular element at a plant often does not solve the problem as it cant uptake it to begin with.
I do add some extra Mg to my Jacks Hydroponic formula, however, I understand my exact PPM of Mg in my feed and by looking at the plants and I can track if there is a problem. I take pictures everyday for review, just to check for deficiencies.
I dont find XJ to be a Mg hungry strain at all.
Calcium Nitrate is Nitrogen and Calcium, you dont need to add these to your feed with Fox Farms nutes im sure. CaNo3 is needed to complete Jacks Hydroponic. Formulas are often a two part because of flocculation. Calcium does not mix well with Phosphorus and Sulfur. Jacks has P and S so you mix that up and put it in the reso. You mix up the C seperate, in this case CaNo3. They have balanced the formula for the N from the Ca No3. Together they make the complete mix. I would not mess with this unless you were using Jacks formula. Use what you know.
Again Jacks and Ca No3 = Bliss, thats what I know and Hydro is what I grow.
