Hello guys. I am finding out I suck at growing. I have been having issues with one of my plants. The leaves were getting yellow. It was suggested to transplant them from solo cups to bigger pots. I used 1 gallon. The leaves went back green and looked good for a couple of days. Now it’s back to yellow and worse than before. Any help would be appreciated. I have another plant exact same everything and it’s fine
