I had been slowly giving them nutrients and they were good all the way up to 700 ppm, but the last res change I added to much ionic bloom 550 ppm and didnt want to drive back to the store to get more water. So with the nutrients should I put in 250 of the calmag and do half strength on the ionic bloom till they start looking better. Also I have Hydroguard is that anything like cannazyme and is there any harm in using it. Stinky should I also have the res aerated like the person in the fist post said?
