As the title says. Plant is about 4 weeks into flowering and is having this issue. Certain leaves are yellowing with the center being green. Sorry for the lighting can get better pics later.
Hard to tell with the lighting. Looks like magnesium deficiency but if the upper growth is as dark as it looks and tips pointing down could be to much nitrogen causing other issues. Flush it and carry on feeding bloom not grow that’s my opinion Sent from my iPhone using Grasscity Forum
Its iron. U have green veins and yellowing dying leaves. Very easy to spot that Sent from my VS500PP using Tapatalk
