|Post subject:||Uneven growth|
I am new to farming and mostly looking to reduce the grocery bill. My 3-month old indoor aquaponics system is experiencing a very odd issue: the plant growth is uneven - see photos attached. Most plants sprouted from seeds and quickly grew to baby size but then just stopped growing, with an exception of plants on the bottom right of the grow bed. I have Kang Kong (bottom left), spring onion (bottom middle), chinese broccoli (top right) and spinach (top left and bottom right). The top left spinach plant in the picture was originally planted on the bottom right corner, then transplanted to where it is now, the growth stops the day it was transplanted.
I looked up causes of growth stunt and the most common problem is iron deficiency. I went out and bought some EDDHA Chelated Iron. Added to the tank as per instruction (my fish tank now has a slight pink tint). The system has been running for about a week but I see zero changes.
The water-in pipe is clear plastic and I notice heavy algae growth where it is exposed to light. I went ahead and cover some of these sections with black tape. I suspected the algae is consuming all of the nutrients but how come a section of the grow bed is still fine, shouldn't nutrients in the water be distributed evenly?
What else could I be missing? I a bit hesitant to buy more test kits as I have already well blown through my budget. I am mildly frustrated with the system after so much effort and money spent so any help is much appreciated!
