I mixed 1/2 teaspoon CalMag, FoxFarm Grow Big, and FoxFarm Tiger Boom into 1 gallon of distilled water and PH'd it to 6-6.5. The PPM level was 280PPM. I mixed it to feed some older pants, but not thinking, I used it on one 4 day old seedling and three 10 day old seedlings that are growing in FoxFarm Ocean Forrest. In your opinion and experience, do you think they should be alright, or should I flush it out now to be safe? .
