I am trying to figure out this problem. I noticed that the new shhots are starting to yellow. Im using the minimum amount ok f cal-mag at 3ml gal. Also im using Sumatran natural bat guano at 8-3-1 npk. Ph is at around 7. On a 18-6 light cycle. Humidity is fairly low due to the surrounding at around 35-40%. 75-80° Using filtered water. Anyone know why they are yellowing?
