well i am saying that after i flush there will be nothing in the soil anymore so i should feed right after? Or should i just flush then let dry out?

I watered multiple times with full strength cal-mag My well waters calcium hardness is 340 ppm but the thing I thought about was after I flushed with the 7.2 ph water, I immediately watered like a hour later with nutrient solution so that would have lowered the ph of the soil me thinks! Also i added a mild cal-mag solution in a foliar spray I did and the leafs look a little healthier! So should I water with cal mag or do the epsom salt thing? Im getting the soil ph tested this after noon so we are going to track down this culprit and obliterate it! and guise chill you're both obviously very experienced it just seems you both have stood on different sides of the same problem! Always more than 1 way to skin a rabbit amirite?

Drop the CalMag completely. Your well water as I suspected contains enough calcium. And by adding CalMag yes you are adding Magnesium, but your also adding more calcium you do not need. Just add 1/2-3/4 tsp of epsoms salts in place of the CalMag. This will help get the two(Mg/Ca)back in proportion. See even before you mentioned you are using well water and its hardness I already pretty much figured out you issue. But then again what do I know.........And your mediums pH is what it is. Simply pouring pH watered through will not alter it. Dont worry about your mediums pH as I bet it fine.....

Occurred before the flush and still deficient. You can flush again if you like but its not going to help. You should be treating a basic Magnesium deficiency...

And 99% of deficiencies are just that, basic deficiency. If pH were an issue then most likely it would showing more symptoms than just a Mg problem. Salt build up is blamed for many. Little secret for you. Salt build has a tendency to precipitate to the TOP of the medium, showing as little crystals forming on the surface. That plants shows one issue and one issue only, a Mg def. OPs water is 7.2 which is just fine and probably just contains a bit to much calcium and/or carbonates that is throwing the balance between Ca and Mg off. The addition of epsoms salts too his diet would do them right. I have been growing container plants for decades, what would I know.......

Somewhere along the line new growers have confused the need to pH solutions such as in hydro has bled into soil growing.

Looks like a slight Magnesium deficiency too me. View attachment 1988001

I doubt you have lockout or lockup, the plant looks ok otherwise. Bet your pH is just fine. Cannabis does fine in soil with a pH of 6-8, near neutral being optimal.

Magnesium (Mg) deficiency.
Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green. The tips may also twist.
This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.
