I have had this Pogostemon Stellatus Octopus for about 2 months now. The leaves have all been coming in yellow and very thin and in some cases very warped. I have root tabs from Seachem in the substrate and I have been using easy green once a week. They grow like weeds but don't respond well to trimming and have this color/size issue with the leaves. Is there anything I can try to help my plants?
