CO2. Check it. You added more lighting so your going to need to add more
CO2. It's easy to do with canned CO2, not so easy with yeast. Your also
going to need to add more nutrients but I doubt P is one of them if your tap
has plenty already. Add some tap water and crank up your CO2. Do a good old
water change and scape off all the algae you can and add another CO2 yeast
bottle etc or up the amount of yeast/sugarmix get a bigger bottle for the
brew find a better method of adding CO2 into solution etc.

It's a fast growing plant. You need to keep up with pruning and keeping the
NO3 at decent level. I've done well from 3000-8000K growing it. Fast growers
will show signs of nutrient deficiency first. You may just need to add more
CO2. If you add lots of distilled water what do think your KH will be after
sometime? Even at a pH of 6.8....if your less than 2KH, your in the red so
to speak. My bet is CO2. It's always the first place to look if you ever
have a problem. Especially with Yeast CO2. If you have NO3's then it's the
CO2. Adding some tap water and keeping the pH at 6.8 and a KH of 4 will
solve what ails thee. Try it and see. You have plenty of fish so the NO3 and
P should be okay even if low. Test the KH and see.
