all flushing does is rid the plant of salts. Salt build up can cause lock out. Yours doesn't appear to be locked out. Just add more calcium. Be careful if using cal mag mix. Too much mag will lock out cal and vice versa. I thinks who ever came up with cal mag mix first is not to bright and doesn't know the first thing about horticulture or botany.
an all around nutrient tea I use would work great.
for 5 gal tea
1/2 cup alfalfa meal
1/4 cup kelp meal
brew for 1-2 days. Til foamy.
then right before using add 25 mils pro tekt
1 cup pureed aloe leaves.
water and use as a foliar.
compost tea for 5 gal tea
3 tbsp molasses - aerate for an hour
add a couple handfuls of compost and worm castings
1/4 cup kelp meal.
brew for 2 days.
seed sprout teas (enzymes, minerals, nutes, cytokines, saponins, sugars).
per 5 gal 2 oz or 1/4 cup of corn sees or barley seed
soak for 12 hours
rinse
rest on wet cloth in the dark for 12 hours.
repeat both steps til sprouted. Puree with 1/2 cup of water. Then strain into 5 gal of water.
aerate / brew for a couple hours. Don let go past 4 hours or becomes acedic / herbicide.
when seeds sprout the endosperm releases all kinds of goodies .
