Well, the bulbs are only a couple months old and I haven't moved it at all. The fixture is a dual 48 wat T5HO (8 hour photoperiod) which is a lot of light for being a 20 gallon. This is the first sword that has done this under the light. When my rubin sword was larger, it never did this. Assuming it is getting the nutrients it needs from seachem root tabs and pressurized CO2, should I expect to see problems arising from this plant?
Since I am not completely sure on the meaning, is reaching an increased rate of growth to get closer to the light source?
