Hey man, i had the same thing happen to me. Basically, what i understand is the Fish Mix makes a high PH for your plants, and some of the more sensitive types of plants will eventually become unhappy. So what i did was wait until the next watering (the dry/wet cycle is important!) then just go with some plain water. try going with bloom nutes soon, also : they often have the correct PH, and can start your flowering aswell. btw : i'm adding molasses every watering now, and my babies love it ! A+ 💪
