All,
Just wanted to see if I am way off base here... I am reading some other sites (I won't mention which ones, but they are quite popular) and it seems like they toss out fertilization recommendations at random. For some plants they recommend low nitrates, others high nitrates etc... etc... Some quotes as examples:
In regards to L. repens:
"Lean nitrate levels (~5 ppm), high phosphate levels (~1.5-2 ppm), and heavy iron/micronutrients dosing will help produce intense colors out of this plant. Some hobbyists have noted that 9325K plant bulbs will also enhance red coloration."
In regards to Rotala Macrandra
"If nitrate is pushed too high (20 ppm or more), the plant may actually stunt. Low NO3 levels (10 ppm or less) coupled with high PO4 levels (1.5 to 2 ppm) lead to very compact, lush, bright red growth."
Is there any truth to such statements? They seem kind of random/un-founded. It is my understanding some emersed plants change color etc... in different soil PHs and some plants will produce more flowers compared to fruit when NO3 levels are high. Not sure if this translates to statements such as above.
I am going to try the L. Repens myself and see what I come up with using EI.
Cheers,
John
