Hi jmontee. Thanks for the response. My fert regime is API Leafzone, 20ml every three days and Seachem Flourish Excel (1 cap) every 3 days. I ran a water test and my pH is at around 6.8, Nitrate 0-10ppm, Nitrite, 0ppm and ammonia is 0ppm. Having read a few more threads I'm thinking my photo period may be a little long to say I just introduced my plants to this new hi tech set up.
And yes you are right I wanted to introduce some more plants, add a little more color too.
