Grab some ph strips and test your water. It looks like it needs Nitrogen, but I thought FF soil has nutrients already, and should last you more than 10 days... so I wouldn't suggest feeding it until you have checked the ph.
bigtopsfinn Reviewed by bigtopsfinn on . Plant Discoloration I've been growing 3 plants. All receive the same treatment. 2 are dark green and beautiful but one is a lighter green. Like a pale unhealthy green. On top of that it has some blotches that are even a lighter green and the condition seems to be getting worse. What can be the problem? Plants are over 2 weeks old and I noticed the condition about 3-4 days ago. Rating: 5
