Undoubtedly this is partly due to the increased lighting that I have now (before starting to dose ferts, I only had one 13w bulb, 6 hours/day). So what I'm wondering is, is there anything that I'm NOT adding that I need to add, or anything I'm ADDING that I need to increase/decrease to give the plants more of the upper hand?
Also another problem, I bought a Vals and the edge of one leaf was kind of yellow when I bought it. It spread up the leaf so I cut the leaf off. Now many of the leaves are turning yellow on the tips and dying. What is this a symptom of?

Ack ! Edited in horror: I forgot about your low light limitations. Your choice of Val seems very appropriate under the circumstances. I have done this in micro systems, but I started with no less than 30 small Italian Val W/ 7 watts of light in a 2.5g hex (Presently a vigorous little jungle W/ little or no algae at all). I'd perhaps gently clean the algae off, and maybe give them a spritz of peroxide for a few minutes, and maybe increase the number of val,but stick with smaller varieties. I'd keep the nutrients a bit lean and fall back on fert plugs for the swords (Only if neccessary !) HTH, Prof M
