Barney's Farm Promo seeds

I've been trying to fix the strawberries, looked like they were cal mag deficient, but I gave them some cal mag. but they still turning yellow with spots. Maybe it was overfed and locked out? I am open to ideas. I flushed them yesterday once anyway. Maybe I will give them dense bud compactor one more time(3rd) next feed, then just flush them till they're ready. Oranges look slightly overfertilized, tips are a bit burnt, and leaves are curling down, so I cut back on the nutes a bit. They need like 2 weeks maybe more. Buds look huge on the oranges!
