Please take what I have to say with a grain of salt, but I would flush the plants with lots and lots of dechlorinated water. Just flush them with a bunch of water one time and wait till the top 1/4 inch of soil is dry untill you water them again the next time. I have heard that ductchpassion's blueberry is very nutrient sensitive, and also sensitive to being dried out, so don't wait too long to water again. But also don't keep your soil soggy . And I would dilute w/e I gave them, more diluted than recommended. The first plant I grew I used potting soil and just watered it. I just let the plant absorb all the nutrients from the soil before I starting feeding it nutes. My first plant grew for 6 weeks off of just soil and water, until it needed fed water-soluble nutes. I just wanted to share that, hope it helps
