Magnesium lockout

If a plant is suffering from magnesium lockout due to soil ph, will it absorb magnesium from foliar spraying?

yeah bit of epsom salts disolved in warm water added to your foliar spray will be good couple of days and you'll see them start to re-green

Add them in addition to the nutrients already in my spray?

no i usually just use it with ph'd water make sure you dissolve it in warm water properly its the most important bit

there isa product called cal mag use it as foliar and root feeding should b nice in the morning

I have been using Grow Big 6-4-4 for foliar spraying all along and it contains micronutrients. The seeds are sadhu but they are F2. Out of 14 seeds only 3 are showing this more yellow color and those are otherwise growing exactly like the other 11 and are getting the exact same nutes. Having just 3/14 like this makes me wonder if this may simply be a recessive phenotype that didn't show in the F1 seeds. Does anyone have any experience with rates of recessive phenotypes among F2 seeds?
