Most likely an iron deficiency.... get some chelated iron... and add a scoop...

What's your pH... 7.2+...

i was trying to find a guide on deficiency in leaves a basic guide ( with photos) for indoor growing. because you are indoor growing light may also be an issue . hard to say without a pic


if your going for a light read this artical :

quick question. didnt really think it needed another thread. i've always made a little rusty water for yellowing plants in the dirt. i just allow a metal scrub pad to sit in some water then pour a little into a larger water bucket to dilute it then pour it on my plants. seems to have always worked. so just wondering if this can be used in very small quantities in aquaponics? or does this just kill fish?

that won't really get your plants any "chelated" iron..
go with maxicrop with iron

Don't give up on the herbs!... give up on the LED's!!!


Yep!... ESPECIALLY the cheapo ebay ones. I have lost count of how many customers have quizzed ne about LED's, not taken my advice to save their money (or buy a CFL), bought the LED's then binned them after a few months.

I only have one customer that's having any success with LED's and he's running a 450w array from an American manufacturer... not exactly power saving and the results still aren't up to HID (HPS or MH) levels. Also, the 450w array he bought retails in Oz for up to $1600 and the US for about $900

Over your aquarium system a 130w Compact Fluoro (CFL) in 6400k would work a treat on herbs and small leafy greens like fancy lettuce.
