hi- i bought this 2 days ago at the pet store and i wasnt aware it shot up a shoot to the surface with a bud at the tip. it seems like it is ready to flower. any tips on what i should do? light is 1.5 wpg- left on for 12-14 hours a day. dosing flourish, and excel. 20 gallon tank with aquaclear 70 filter. clean as a bell inside- all nitrite, ammonia and nitarte are at 0. ph is stable; tank is over 2 years old and is very very well established. should i lower the water level to below the tip of the bulb? plus, what should i do after the bud is done flowering? any tips would be appreciated
