Hey guys, looks like maybe I’m having a P deficiency. I’m here hoping to confirm or to find the actual cause. DWC 5 gal res with 3 gal water with fox farm nutes. Adding Hydroguard 4 ml every res change. I give 2 ml big bloom and 1 1/4 ml grow big. Temps no higher than 75 or lower than 70 Fahrenheit. Humidity is cruising around 45-55%. Roots are beautiful and plentiful.
