    this plant is usualy a fast grower, now that i have planted cuttings in my new 1.2, the new growth is yellow, is it a shortage of light or ferts? substrate is only silica sand and only 1 35W tube please id and advise

    Cant tell on my phone but it looks like H. Semensis or H.Corymbosa, this is typically a very fast grower but under your low lighting should be moderate 2 slow, the yellow is usually a sign of an iron/fe defficiency (which could be sorted out through simple EI dosing or by planting normal iron nails at the base of the plant)

    However in your case I would say your lighting is not nearly enough 2 support plant growth, I would suggest at least 5 more bulbs ranging from 4000-10000k spectrum and start dosing some sort of ferts asap otherwise these plants will slowly melt..

    Good luck man :)

    the light is defnitley not enough but theres alot of sunlight on the tank during the day, the swords are doing fine, but theyve got nails at the roots and some potting soil, i am adding some seachem ferts, but its a new setup, wil ad some more, and ad some more nails

    thanks carl p
