I've scowered the forum but can't find what I'm seeing on one of my plants
two weeks into 12/12. The leaves are yellowing (light green) ad the veins are really yellowing. Some leaves that are still generally green show the yellow veins. What could be the problem. My water pH I try to keep arount 7.0 but could be as high as 7.2. The first week into 12/12 I used a diluted Peters Bloom Plus. Help please... |

the little white spots in it could be pH "hotspots". i would try to stay away from the 7.2 pH for the meantime. it could also be a pH flux. where it has change rather drasticly in a short amount of time. some ferts when the break down have pH changes, soils too.
