Dill, nutrient deficiency?
« on: August 20, 2016, 04:01:42 16:01 »
I have a small (c. 100l) flood & drain media based system lightly stocked with a few cold-water minnows, gold barbs and corys.  I keep it in the conservatory and use it for growing kitchen herbs. 

One of the grow beds is doing OK- planted out with parsley & sage.  I planted out a few dill & basil seeds recently in the second grow bed.  The seedlings are coming through but are growing very slowly and there are signs of a nutrient deficiency in the leaves.  There doesn't seem to be any yellowing in the leaves.  Nitrates are up (10 mg/l (ppm) & higher than I want.  Ph is on the mark around 6.8.

My working assumption is that I have a (non-nitrogen) nutrient deficiency restricting uptake of nitrates and causing problems for the new seedlings.  Could it be an iron deficiency?  Potassium?  I've attached a pic.
