these 2 are only 3 weeks old, my issue is that jus last night, I mixed up a batch of 0-4-8' today I get up to that they are a lil droopy, and noticed that roots were starting to turn light brown. is this from my lucas formula? well to tell you the whole truth, I started out using b.c. boost, b.c grow, and whatever else comes in the ''recipe for success'' box. you know what I mean. I instantly had light brown slime floating everywhere, but it was mostly on my 5'' round airstones. what is this? bought new airstone and cleaned out the res. now I have a droopyness after the switch to lucas, why would this happen? any help is very appreciated, thanks in advance.
