I have been having this problem for over a month now and it’s beginning to really affect my plants. At first it was just one of my plants but now all my new seedlings I repotted seem to show the same signs of my older plant. All plants grown in ffof no nutes.Humidity around 50% ,63-75 degrees. Grown under 8 bulb t5. My water is ph 6.5. I tested one plant and the runoff ph was around 4.5. What is this it’s slowly killing my plants. Sent from my iPhone using Grasscity Forum
Start flushing with PH adjusted water till you reach the desired number. If adding nutes adjust PH after the nutes are added
